The area of a square in square feet is represented by z² + 8z + 16.

Luden [163]

Answer:

Side length: z + 4

Perimeter: 64

Step-by-step explanation:

Hello!

Since the area of a square is the square of the sde length,

using the special binomial product formula: (a+b)² = a² + 2ab + b²:

z² + 8z + 16
(z + 4)²

The side length of the square is (z+4)².

The perimeter is 4(z + 4), where z is 12:

4(12 + 4)
4(16)
64

The side length is z + 4, the perimeter is 64

Answer:

Step-by-step explanation:

10). AD = BC [If ABCD is a parallelogram]

3x + 1 = 6x - 4

6x - 3x = 1 + 4

3x = 5

x = $\frac{5}{3}$

11). If ABCD is a parallelogram,

AB = CD

5x - 8 = 2x + 7

5x - 2x = 7 + 8

3x = 15

x = 5

12). If ABCD is a parallelogram,

AB = CD

AB║CD and BD is a transversal intersecting these parallel lines.

∠ABD ≅ ∠BDC [Alternate interior angles]

4x - 1 = x + 38

4x - x = 38 + 1

3x = 39

x = 13
