Step-by-step explanation:

substitution

Hi! I'm happy to help!

To first solve this, Let's see if we can simplify our expressions using the order of operations: our original expression cannot be simplified. The first expression cannot be simplified. The second expression we can multiply the outside by the parenthesis by the inside, same with the third and fourth.

(make sure everything outside of the parenthesis is being multiplied by each part inside of the parenthesis)

9a²b²

9a²b²

3ab(3b+2a)

ab(9b+6a)

b(9ab+6a²)

9ab²+6a²b

3ab(2b+3a)

ab(6b+9a)

b(6ab+9a²)

6ab²+9a²b

3a²b²(2b+3a)

a²b²(6b+9a)

b²(6a²b+9a³)

6a²b³+9a³b²

Now that we have all expressions fully simplified, let's compare to see which one matches.

Our first expression is nowhere close to what our original expression is, 1 is incorrect.

Our second expression is close, but it has the 9 and the 6 flipped, even if we rearrange the expression like this, 6a²b+9ab², it still doesn't match, so 2 is also incorrect.

Our third expression has the correct numbers, variables, placement, and exponents, so 3 is correct.

Our fourth expression has incorrect exponents, the expression made every variable multiplied by ab an extra time, so 4 is incorrect.

In summary, you should pick number 3, because it is equivalent.

I hope this was helpful, keep learning! :D

Answer:

The answer is: The sum of x and y is a rational number.

Step-by-step explanation:

x is a rational number (any).

[tex]\frac{2}{3}[/tex] is a rational number too.

So, the sum of x and y will also be a rational number.

Answer:

[tex]4 {n}^{5} + 3.5 {n}^{5} + ( - 2.1 {n}^{5} )[/tex]

first create a bracket:

[tex] = ( {4n}^{5} + 3.5 {n}^{5} ) + ( - 2.1 {n}^{5} )[/tex]

then solve the first bracket:

[tex] = {7.5 {n}^{5} } + ( - 2.1 {n}^{5} )[/tex]

then open the remaining bracket:

[tex] = {7.5n}^{5} - {2.1n}^{5} [/tex]

carryout the subtraction operation:

[tex] = (7.5 - 2.1) {n}^{5} \\ { \boxed{ = {5.4n}^{5} }}[/tex]

Answer:

Answer:

-1 C

Step-by-step explanation:

Mean = Average

To find the mean simply add all the values and then divide that by the number of given values

So first add the 4 values together

1.5 + -2.6 + -3.4 + .5 = -4

Then divide the sum by the number of values ( there are 4 values )

-4 / 4 = -1

The mean temperature is -1

Answer:

fig.1 No, fig.2

Step-by-step explanation:

fig.1 is no because "a" has more than one output therefore it's not a function.

fig. 2 is yes because "a,b,c,d" have different outputs but not more than one

Answer:

-1.13

Step-by-step explanation:

Each space or unit in the number line is equidistant to 0.01.

Answer:

-1.13

Step-by-step explanation:

you can count the units from -1.1 and you will find out this

its the correct answer

You can even add 2 units from -1.1

-1.1 can also be written as -1.11

so -1.11 + 2

= -1.13

Answer:

y = -1/2x - 8

Step-by-step explanation:

Slope: ( -7 - - 6 )/(-2 - - 4) = (-7+6)/(-2+4) = -1/2

Point : (-4,-6)

y - - 6 = - 1/2(x - - 4)

y+6= - 1/2(x+4)

y+6= - 1/2x - 2

y = - 1/2x -2 -8

y = -1/2x - 8

Answer:

x = -5

Step-by-step explanation:

If you want the value of x and it should be true we first need to find the value of x

4 - 3x = 19

-3x = 19 - 4

-3x = 15

x = 15/-3

x = -5

Answer:

It is 136

Step-by-step explanation:

[tex]h + {k}^{2} - j[/tex]

substitute respectively as in question:

[tex] = 3 + {(11)}^{2} - ( - 12)[/tex]

open brackets:

[tex] = 3 + 121 + 12 \\ = 136[/tex]

Answer:

136

Step-by-step explanation:

Given

h + k² - j ( substitute the given values into the expression ) , that is

3 + 11² - (- 12)

= 3 + 121 + 12

= 136

Step-by-step explanation:

Answer:

Step-by-step explanation:

The three segments make a triangle with sides 6, 7 and 12 m.

We need to find the angle opposite to side 7 m.

Use the low of cosines to work out the angle x:

[tex]\\ \rm\longmapsto x-5=41[/tex]

[tex]\\ \rm\longmapsto x=41+5[/tex]

[tex]\\ \rm\longmapsto x=46[/tex]

Hence

[tex]\\ \rm\longmapsto 45<x<47[/tex]

Answer:

120 fluid ounces

Step-by-step explanation:

1 cup = 8 fluid oz

Multiply 15 on both sides (since there is 3 pitchers and each is 5 cups, so 3 * 5 = 15 cups in total for all 3 pitchers) and we get 15 cups = 120 fluid oz.

So that's our answer

Hope this helped!

The height of the tower is 120 feet

The given parameters can be represented using the following ratio

Ratio = Height : Shadow

So, we have:

Tower : 80 ft = 6 ft : 4 ft

Express as fraction

Tower/80 = 6/4

Multiply both sides by 80

Tower = 120 feet

Hence, the height of the tower is 120 feet
