Answer:
Step-by-step explanation:
3/4
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
Hello!
*I'm not very good at algebra, so I am not 100% sure this is correct!*
w = cost of washer
d = cost of dryer
w + d = $586
w = d - 64
d - 64 + d = 586
2d = 586 + 64
2d = 650
d = 650 / 2 = 325
586 - 325 = 261
Check 325 - 261 = 64
So, the dryer costs $325 and because the washer is $64 less than the dryer, it costs $261.
|12x + 1| = 10
Remove the absolute value term and make two equations:
12x +1 = 10
12x +1 = -10
Now solve for both x values:
12x +1 = 10
Subtract 1 from both sides:
12x = 9
Divide both sides by 12:
x = 9/12
12x +1 = -10
Subtract 1 from both sides:
12x = -11
Divide both sides by 12:
x = -11/12
The answer would be (-11/12, 912)
The answer is no i do not agree
