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

D. 2x2 – x+8
f(x) = 2x; g(x) = 3x^2 + 1
(f x g)(4) is 2x(3x^2 + 1)
2x(3x^2 + 1)
6x^3 + 2x
6(4)^3 + 2(4)
6(64) + 8
384 + 8
392
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
