Naomi's square bedroom has an area of 90 square feet. What is the length of one of the walls? Round to the nearest tenth if necessary.

9.48 ft

Step-by-step explanation:

Step one:

given data

Naomi's square bedroom has an area of 90 square feet

Area of the room = 90 ft^2

Required

the length of the side of the room

Step two:

we know that area is

A= L^2

substitute

90= L^2

L= √90

L=9.48 ft

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
