Answer:

a.) 2(x + 2) + 2 = 2(x + 3) + 1

b.) 2x + 3(x + 5) = 5(x – 3)

e.) 5(x + 4) – x = 4(x + 5) – 1

Step-by-step explanation:

a.) 2(x + 2) + 2 = 2(x + 3) + 1

0 ≠ 1

b.) 2x + 3(x + 5) = 5(x – 3)

0 ≠ -30

c.) 4(x + 3) = x + 12

x = 3

d.) 4 – (2x + 5) = (–4x – 2)

x = -½

e.) 5(x + 4) – x = 4(x + 5) – 1

0 ≠ -1

Please help me with this question.

Answer: a) 110√2 meters

b) 2.42 hectares

Step-by-step explanation:

a) Since it is a square, the diagonal cuts the square into two 45-45-90 triangles where the diagonal is the hypotenuse. Therefore, the sides are length x and the diagonal is length x√2.

$x\sqrt2=220\\\\\\x=\dfrac{220}{\sqrt2}\\\\\\x=\dfrac{220}{\sqrt2}\bigg(\dfrac{\sqrt2}{\sqrt2}\bigg)\\\\\\x=\large\boxed{110\sqrt2}$

b) Area of a square is side squared. 10,000 meters² = 1 hectare

$A=(110\sqrt2)^2\\\\.\quad =(110)^2(\sqrt2)^2\\\\.\quad =12100(2)\\\\.\quad =24200\ \text{meters}^2\\\\.\quad =\large\boxed{2.42\ \text{hectares}}$
