Answer:

1. C

2. C

3. 48 in

4. C

Step-by-step explanation:

1. A perfect square is a number that can be expressed as n * n, where n is an integer. A perfect cube is a number that can be expressed as n * n * n, where n is an integer again. The three given numbers suffice both properties, hence the answer is C.

2. The volume is 9 * 9 * 9 = 729 cubic inches. We want to fit 1000 cubic inches in the box, so not everything wil fit as 729 < 1000.

3. The side lengths of the square, s, may be solved by s^2 = 144, which gives s = 12. So the perimeter is 4s = 48.

4. The area of the square is 64 square inches, so each of the side lengths measures sqrt(64) = 8 inches.

Evaluate and simplify <br><br> F(x)=3-6x^2 for f(x+3)
Olegator [25]

Insert x + 3 instead of x into the equation of the function f(x):

f(x) = 3 - 6x²

f(x + 3) = 3 - 6(x + 3)²

use (a + b)² = a² + 2ab + b²

= 3 - 6(x² + 2(x)(3) + 3²) = 3 - 6(x² + 6x + 9)

use distributive property

= 3 + (-6)(x²) + (-6)(6x) + (-6)(9) = 3 - 6x² - 36x - 54

combine like terms

= -6x² - 36x - 51

<h3>Answer: f(x + 3) = -6x² - 36x - 51</h3>
