15x^3-12x

Begin with sorting out what 15x^3 and 12x have in common

15 and 12 are both divisible by 3, so divide 3 by both 15 and 12 and put 3 on the outside.

15x^3 and 12x also both have an x in common, so divide the x's (which is basically subtracting them).

3x(5x^2-4)

Vladimir79 [104]

Answer:

0.979%

Step-by-step explanation:

Given that:

Estimated value = 825 ;

Actual value = 817

(|Estimated value - Actual value| ÷ actual value) * 100%

(|825 - 817| ÷ 817) * 100%

(8 / 817) * 100%

0.0097919 * 100%

= 0.979%

= 1% (nearest percent)
