The expression is equivalent to (f circle g) (x) will be (3x+2)²+1. The correct option is D.

A number is obtained by dividing another number by itself without leaving a leftover. To put it another way, if multiplying two whole numbers produces a product,

The given expression is;

[tex]f(x) = 3x + 2 \\\\ g(x) = x_2 + 1[/tex]

[tex](f g)(x) =g(f(x)) =g(3x+2)=(3x+2)^2 +1[/tex]

The expression is equivalent to (f circle g) (x) will be (3x+2)²+1. Option D is correct.

Answer:

x=6

Step-by-step explanation:

FG is similar to MN just like GH is similar to NP.  GH is 20, which is double NP,10. Then, MN should be half of FG, 12, so 6 is your answer.

The value of x, which is the length of ST in the given similar polygons is: 2.4.

If two shapes are similar to each other, the ratio of their corresponding side lengths would be equal.

Thus, since both pentagons are similar, we would have:

CB/RQ = DE/ST

Plug in the values

5/6 = 2/x

Cross multiply

x = (6 × 2)/5

x = 12/5

x = 2.4

Therefore, the value of x, which is the length of ST in the given similar polygons is: 2.4.

Height of base (x) is 9cm exact

Step-by-step explanation:

A quadratic equation is an equation whose leading coefficient is of the second degree. The factored form of the quadratic equation x²-x-2 is (x+1)(x-2).

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.

It is written in the form of ax²+bx+c.

The factored form of the quadratic equation can be done in the following manner,

[tex]x^2-x-2\\\\= x^2-2x+x-2\\\\=x(x-2)+(x-2)\\\\=(x+1)(x-2)[/tex]

Answer:

9.

Step-by-step explanation:

6 9 12 15:-  multiplying by 3.

Answer:

B) 9

Step-by-step explanation:

When looking in both the horizontal and vertical direction of the missing space, we can see that the difference between the two numbers, 12 and 15, is 3.

15 - 12 = 3

Using this, we can see that each space on the second row and second column change by 3. Therefore, when looking at the missing space in the sequence, we can figure out that it is 9 by adding 3 to 6.

Answer:

A

Step-by-step explanation:

Starting amount =                             307.50

1 month saving = 100

5 month saving = 5*100                   500.00

Total so far                                         807.50

Let the total amount be x

75% *x = 807.50

75/100 x = 807,59                              Multiply both sides by 100

75 x = 807.50 * 100                          

75 x = 80750                                      Divide by 75.

x = 80750 / 75

x = 1076.67

That is not the answer. That's the total cost of the laptop.

The amount needed is

Amount needed = Total Cost - what has been saved

Amount needed = ????

Total Cost = 1076.67

What has been saved = 807.50

Answer

Amount needed = 1076.67 - 807.50 = 269.17

Answer:

2y+1 is the correct answer.

Answer:

rst = ust + usr

6x+12 = 78 + 3x - 12

3x = 54

3x+66 = 54 + 66

3x +66= 120

thus rst = 120

The measure of angle ∠RST in degree is 156°

The measure of angle is the amount of rotation performed by initial side to get the terminal side. A complete angle is divided by 360 equal parts we get 360 number of small angles. Each of these small angle has measure 1 degree.

Given that, ∠RSU=78° , ∠UST=(3x - 11)° and ∠RST=(6x + 12)°

Now, ∠RSU+UST=∠RST

Putting the values of ∠RST and ∠UST we get,

78 + (3x - 12) = 6x + 12

78 + 3x - 12 - 6x - 12 = 0

54 - 3x = 0

3x = 54

So, x = 54/3=18

Therefore, (6x + 12)°=(6×18 + 12)°

=(144 + 12)°

=156°

Hence the measure of angle ∠RST is 156°

Answer:

6 days

Step-by-step explanation:

If the first bricklayer can build a wall in 15 days, he can build 1/15 of a wall in one day.

If the second bricklayer can build a wall in 10 days, he can build 1/10 of a wall in one day.

Therefore, if they work together, in one day they will complete

1/15 + 1/10 = 1/6

of the wall.

Since they can complete 1/6 of the wall in one day, they can complete 6/6 or one wall in 6 days.

Answer:

d.  64 cm²

Step-by-step explanation:

Separate the shape into two rectangles (see attached image).

Formula

Area of a rectangle = width × length

Rectangle 1

Area = 2 × 12

        = 24 cm²

Rectangle 2

Area = 5 × (10 - 2)

        = 5 × 8

        = 40 cm²

Total Area

Total area = Area of Rectangle 1 + Area of Rectangle 2

                  = 24 + 40

                  = 64 cm²
