Question

1.2 Express the area of ​​each of the squares. Then, simplify each expression using
remarkable products.

Remember: area of ​​the square A=l²
I= side length

1.3 Find two equivalent expressions that represent the volume of the cube.
Remember: Bucket volume

V= a³
a= edge length

Answer 1

Answer:

Area of square A is x² + 6x + 9.

Area of square B is 4a² - 4a + 1.

Volume of the cube is (x - 2)³, or x³ - 6x² + 12x - 8.

Step-by-step explanation:

Area of square A = I²

I = side length

I = x + 3

(x + 3)² = x² + 6x + 9

Area of square B = I²

I = side length

I = 2a - 1

(2a - 1)² = 4a² - 4a + 1

V= a³

a = edge length

a = x - 2

(x - 2)³ = x³ - 6x² + 12x - 8
