Answer:
b= 2x²; c = 4; 3 = 3 ; g = 6x
Step-by-step explanation:

512 feet because to find the area u multiply length times width and since your givin the area and width you divide the area by the width
It all depends on what you are comparing it to... if you want what fraction of a meter it is...
There are 10 decimeters per 1 meter so 1 dm is 1/10 of a meter which means 6 dm = 6 × 1/10 = 6/10 = 3/5
6 dm = 3/5 m
Answer:
see explanation
Step-by-step explanation:
The side of the square = x + 2, thus area is equal to
(x + 2)² ← expand using FOIL
= x² + 4x + 4
Given area = 7 then
x² + 4x + 4 = 7 ( subtract 4 from both sides )
x² + 4x = 3 ← as required
