The answer is 100X because if you do 5x-4x first it will be 1x. Later on, if you do the exponent you have 1x times 1x. Then you do 1x+9x = 10x

Then you do 10x times 10x because of the exponent is telling you how times you do it and it equals to 100x.

Answer= 100x



I hope this helps YOU!

The diameter of a circle is 14cm. Which TWO statements are correct?<br><br> A
Reika [66]

Answer:

(a) and (e)

Step-by-step explanation:

Given

d = 14cm

Required

Select the true statements

First, is a statement about the area.

The area is calculated as:

Area= \pi*\frac{d^2}{4}

So, we have:

Area= 3.14*\frac{14^2}{4}

Area= 3.14*49

(a) is true

Next, is a statement about the circumference.

This is calculated as:

C = \pi d

So, we have:

C = 3.14 * 14

(e) is true

The length of a living room is 12 feet and its width is 1012 feet. The length of the room is being expanded by x feet. Choose an
Ivanshal [37]

Answer:

Option C. 10.5(12 + x) square feet

Option E. (126 + 10.5x) square feet

Step-by-step explanation:

step 1

Find the area of the original living room

we know that

The area of the original living room is equal to

A=LW

we have

L=12\ ft\\W=10\frac{1}{2}\ ft=10.5\ ft

substitute

A=(12)(10.5)=126\ ft^2

step 2

Find the new area of the living room

The length of the room is being expanded by x feet

so

we have

L=(12+x)\ ft\\W=10.5\ ft

The new area is

A=10.5(12+x)\ ft^2

The expanded form of the expression is

Apply distributive property

A=10.5(12)+10.5(x)\\A=(126+10.5x)\ ft^2
