The figure below represents a building in the shape of a pentagon. Using the scale 1 inch = 94 feet, what isthe perimeter of the building?

Answers

If 1 inch = 94 feet, 4 inches is 94 × 4.

94 × 4 = 376

Add 376 to itself 5 times, or use a simpler method and multiply 376 by 5.

376 + 376 + 376 + 376 + 376 = 1,880

376 × 5 = 1,880

Answer:

The perimeter is 1,880 feet. (20 without the scale applied)

Which statement describes how to solve ^3 squareroot x^2-6= ^3 square root 2x+2

Answers

Answer:

Square both sides and then solves the resulting quadratic equations

Step-by-step explanation:

The equation is 3sqrt(x^2-6)=3sqrt(2x+2)

We can solve this by;

First square both sides;

(3√(x²-6))²=  (3√(2x+2))²

We obtain;

9(x²-6)=9(2x+2)

We simplify to obtain a quadratic equation;

x²-6=2x+2

= x²-2x-8=0

Then we solve the quadratic equation;

x²-4x+2x-8=0  

x(x-4)+2(x-8)=0

(x+2)(x-8)=0

 Values of  x = -2 or 8

Answer:

Cube both sides and then solve the resulting quadratic equation.
