Answer:

x^2.

Step-by-step explanation:

(x+3)^2 -3 (2x+3)

= (x + 3)(x + 3) - 3(2x + 3)

= x^2 + 3x + 3x + 9 - 6x - 9

= x^2 + 6x + 9 - 6x - 9      

= x^2 + 6x - 6x + 9 - 9        Simplify like terms:

= x^2.

Answer:

see explanation

Step-by-step explanation:

Supplementary angles sum to 180°  , then

x + y = 180 , that is

[tex]\frac{1}{3}[/tex] y + y = 180 ( multiply through by 3 to clear the fraction )

y + 3y = 540

4y = 540 ( divide both sides by 4 )

y = 135°

Answer:

well, only 87 people were asked. How did they get 482?

also, they should have asked the people in the library.

Answer:

Step-by-step explanation:

A

A raccoon is 5 more pence than a badger.

r = b + 5

B

Let the beaver's price be be.

be = 3*b

C

Total = 5 + b + 8*be

Total = 5+b + 8*3*b

Total = 5 +b + 24b

Total = 25 b + 5

Answer:

a) What is the cost of a raccoon?

b+5

b) What is the cost of the beaver?

b x 3

c) What is the total cost of a raccoon and 8 beavers?

raccoon = b+5

8 beavers = b x 24   (since every beaver is "x3", you do 3x8 beavers)

Step-by-step explanation:

badger = b pence

raccoon = b+5 pence (since it's 5 pence more expensive)

beaver = bx3 (x3 more expensive than a badger.)

I don't know how much "b" is so just fill in the blank.

Answer:

x=8 y=4

Step-by-step explanation:

eliminate x: make x of two equation equal to each other

2(-3x+9y=12) : -6x+18y=24 ___[1]

-3(2x-8y=-16) : -6x+24y=48 ___[2]

[2]-[1]= 6y=24

substitute y to any equation;

2x-8y=-16

2x-8(4)= -16

2x= -16+32

2x= 16

Answer:

x=14 and y=6

Step-by-step explanation:

-3x+9y=12.............(i)×2

2x-8y=-16..............(ii)×3

Multiplying equation (i) by 2 and equation (ii) by 3 and adding (i) and (ii)

-6x+18y=12

6x-24y=-48

-----------------

0-6y=-36

or, -6y=-36

So,y=6

From (i)

-3x+9y=12

or,-3x+9×6=12

or,-3x+54=12

or,-3x=12-54

or,-3x=-42

So,x=14

the variables b and a are unknown values that represent the number of bananas and apples to be bought. These are next to each of its prices for it to be multiplied once we know the variable.

Answer:

If he can spend $400 +- $50 ($350 or $450) the maximum number of guests at $25 each is 18 and the minimum is 14. If there can be up to 7 guests, he should prepare to have at least 3 tables to ensure everyone gets a seat if he goes with the $450 option.

Step-by-step explanation:

Please mark Brainliest if this helped :)

Division is one of the four fundamental arithmetic operations. The minimum number of tables Ashton should reserve so everyone has a seat is 2.

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that Ashton's budget is $400±50. Therefore, the maximum and the minimum budget that Ashton can spend on the banquet are,

Maximum budget = $400 + $50 = $450

Minimum budget = $400 - $50 = $350

A.) Now, the maximum guest will cost the maximum budget, therefore, we can write

Maximum guest = Maximum budget / Budget per guest

                           = $450 / $25

                           = 18

Minimum guest = Minimum budget / Budget per guest

                           = $350 / $25

                           = 14

B.) Since the minimum number of guests that can come to the banquet is 14, and only 7 people can seat at a table, therefore, the minimum number of tables Ashton should reserve so everyone has a seat is 2.

J (0 , -10)

gradient/slope(m) = 2.

We're asked to find K if K is the X- Intercept.

At the x intercept... the corresponding y value is zero. This concept should be pretty clear.

Reason is...

At the Point where the line touches the x axis...If you trace the y value... It will be at point zero(0).

With this Knowledge

We're able to interprete that the points of K is

(x" , 0)

Where x" represents the x coordinate of K

So

J ( 0, - 10)

K ( x" , 0)

m= 2.

Applying the Gradient/Slope Formula

m = y₂ - y₁/x₂ - x₁

x₁ = 0 y₁ = -10

x₂ = x" y₂ = 0

Substituting

2 = 0 - ( -10)/ (x" - 0)

2 = 10/x"

x" = 10/2

x" = 5.

Coordinates of Point K is ( 5 , 0).

Total Time Taken = 16secs

10a). We're asked to calculate the rate of speed change for the first 5secs.

This is another way of saying "Calculate Acceleration" in the first 5sec of Motion.

Why?

Acceleration is the rate of change of speed or the rate at which speed changes.

acceleration = v - u/t

where v = Final Speed

u = initial Speed.

Looking at the graph

You see that

Initial speed(u) = 1m/s

Final Speed(v) = 9m/s

t = 5secs

Acceleration = 9 - 1/ 5

a = 8/5

a = 1.6m/s².✅

10b)

We're asked to calc "t" from the graph.

Given that the acceleration at "t" untill 16sec(end of motion) is 2m/s².

This simply means that Constant Acceleration was held from "t" to the end of the Motion.

Do not confuse Constant Acceleration for Constant Velocity.

At Constant Velocity... Acceleration is zero(0)

At Constant Acceleration...Velocity Changes Uniformly or at the same rate each second and this is what we're dealing with in this question.

Taking the same step as we used in calculating acceleration above

Given a= 2m/s²

a = v - u/∆t

Where ∆t means time change or difference.

From "t" to 16

The change in time is 16 - "t"

2 = 21 - 9/( 16 - t)

2 = 12/16-t

16-t = 12/2

16 - t = 6

t = 16 - 6

t = 10secs.✅

The perimeter of the triangle will be 5 + √17.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees. The sum of all the sides of the triangle will be known as the perimeter of the triangle.

A triangle DEF with vertices D (3,2), E (4,2), and F (3,-2).

Distance between DE will be

DE² = (4 - 3)² + (2 - 2)²

DE² = 1

DE = 1

Distance between EF will be

EF² = (3 - 4)² + (-2 - 2)²

EF² = 1 + 16

EF = √17

Distance between DF will be

DF² = (3 - 3)² + (-2 - 2)²

DF² = 16

DF = 4

Then the perimeter of the triangle will be

P = DE + EF + DF

P = 1 + √17 + 4

P = 5 + √17

The perimeter of the triangle will be 5 + √17.
