Answer: x=16
Step-by-step explanation:
Answer:
x = 13
Step-by-step explanation:
5x + 25 must equal 7x - 1, because all of the angles in the figure are right angles.
Then 5x + 25 = 7x - 1, and
25 = 2x - 1, and so 2x = 26 and x = 13

Answer:</h3>
2x^2 -5x -2

Step-by-step explanation:</h3>
See the attached for the polynomial long division.
Factor by grouping. Group up the terms into pairs, factor each pair, then factor out the overall GCF.
x^3 + 2x^2 - 16x - 32
(x^3 + 2x^2) + (-16x-32) ... pair up terms
x^2(x + 2) + (-16x - 32) ... factor x^2 from the first group
x^2(x + 2) - 16(x + 2) ... factor -16 from the second group
(x^2 - 16)(x + 2) .... factor out (x+2)
(x - 4)(x + 4)(x + 2) .... Use the difference of squares to factor x^2-16
---------------------------
The original expression completely factors to (x - 4)(x + 4)(x + 2)
The three factors are x - 4 and x + 4 and x + 2
Answer:
100% increase from 100 is 200, the difference is 100.
100% decrease from 100 is 0, the difference is -100
error means that you were quite a long way off from the true value.
