2^3 * 2^-5 = 2^(3 + (-5) = 2^(3 - 5) = 2^-2
6(21)=72 6(31)=186
add 72+186=258
258 is the answer
9/2 or 4.5

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>
X³ = -1000
x = ∛-1000
x = -10
In short, Your Answer would be: -10
Hope this helps!
