-216 is the right answer!
Answer:
Step-by-step explanation:
The two long sides on the left and right and bisected into two equal parts each
That means that since there is an angle in common to the top little triangle and the whole diagram, the little triangle on top and the whole triangle are similar.
The ratio of similarity is 1/2
10/(5x + 5) = 1/2 Cross multiply
(5x + 5)*1 = 10*2
5x + 5 = 20 Subtract 5 from both sides
5x = 20 - 5 Combine
5x = 15 Divide by 5
5x/5 = 15/5
x = 3
Step-by-step explanation:
-3p+6p is 3p

Answer:
x^4
Step-by-step explanation:
(4x^4 + 2x^2 - 6)- (3x^4 + 2x^2 - 6)
Distribute the minus sign
(4x^4 + 2x^2 - 6)- 3x^4 - 2x^2 + 6
4x^4 - 3x^4+ 2x^2- 2x^2 - 6+6
x^4
