Answer:

12

Step-by-step explanation:

f(x) = -x^3 + x^2

Let x = -2

Evaluate the expression

f(-2) = -(-2)^3 + (-2)^2

       = - (-2)*(-2) * (-2)  + ( -2) * (-2)

       = -(-8) + ( 4)

    = 8 + 4

   = 12

(FIXED) Can somebody help me get to x?
Hatshy [7]

18 - 12 = 6. Because the top legs of the 2 triangles are congruent, you divide 6  / 2 to get 3 as their length. Then you can use the Pythagorean Theorem to solve for x.

3^2 + x^2 = 14^2

9 + x^2 = 196

x^2 = 187

x = sqrt(187)

A CD player is on sale for $90 at an electronics store. If the original price was $125, what was the percent of discount
krek1111 [17]
This is the working of how it is 28% discount

Find the amount of discount : $125 - $90 = $35
Divide by the original price : $35/125 = 0.28
Change in to percentage : 0.28 x 100 = 28%

Therefore the percentage discount is 28% off
