We are given with three lengths of a triangle expressed in terms and variables: (3x – 4) feet, (x^2 – 1) feet, and (2x^2 – 15) feet. The perimeter of the triangle is equal to the sum of the three sides of the triangle. In this case, the sum is 3x^2 + 3x -20. When x is equal to 4, we substitute <span>3*16 + 3*4 -20 equal to 40 feet.</span>

Step-by-step explanation:
add all marbles together:
4 (green) + 3 (red) + 3 (yellow) = 10 marbles total
if we pick a yellow marble out of the bag and do not replace it, then we have 2 yellow marbles left.
we need to add marbles again with one yellow marble subtracted.
4 (green) + 3 (red) + 2 (yellow) =
new Total is 9 marbles.
so then we have 2 yellow marbles out of 9 total marbles.
2:9
or 2/9
or .22 (22%)
is the probability
Answer:
32
Step-by-step explanation:
Plug in 4 for c.
(c³)/2 = (4³)/2
First, solve the parenthesis, then divide. Multiply:
4³ = 4 * 4 * 4 = 16 * 4 = 64
Next, divide:
64/2 = 32
32 is your answer.
