Answer: 
Step-by-step explanation:
Simplify:
Answer: x = -5/2 and x = -3/2
Step-by-step explanation:
(2x + 5)2 = 4x (x + 5) +25
4x + 10 = 4x² + 20x + 25
[minus 4x on both sides.]
10 = 4x² + 16x + 25
[minus 10 on both sides.]
0 = 4x² + 16x + 15
ac = 4(15) = 60,then find the factors that add up to 16, which is 6 and 10.
0 = 4x² + 6x + 10x + 15
0 = 2x(2x + 3) + 5(2x + 3)
0 = (2x + 5)(2x + 3)
2x + 5 = 0 2x + 3 = 0
2x = -5 2x = -3
x = -5/2 x = -3/2
<span>First, subtract 132 from 145, then divide 145 by that answer (13) and you will get : 11.1538461538</span>
No, only the value of what you are finding the absolute value of can be a negative. Examples: |-2|=2 |2|=2
Convert 2/5, 1/4 and 7/10 to fractions with like denominators.
Since 8/20,5/20 and 14/20 have the same denominator, add their numerators to add them up.
