Answer:
158 in2
Step-by-step explanation:
15+15 = 30
24 + 24= 48
40 + 40 = 80
= 158
8x + 5 = 3x + 15 |subtract 5 from both sides
8x = 3x + 10 |subtract 3x from both sides
5x = 10 |divide both sides by 5
x = 2
Answer:
0.156
Step-by-step explanation:
15 3/5%=(15+ 0.6)/100=15.6/100=0.156
Answer:
x=2 x=-3
Step-by-step explanation:
4x2+3x=24-x
Subtract 24 from each side
4x^2 +3x -24 = 24-24 -x
4x^2 +3x -24 = -x
Add x to each side
4x^2 +3x+x -24 = -x+x
4x^2 +4x -24 = 0
Factor out a 4
4(x^2 +x -6) = 0
Divide by 4
x^2 +x -6 =0
Factor
What 2 numbers multiply to -6 and add to 1
-2*3 = -6
-2+3 =1
(x-2) (x+3) =0
Using the zero product property
x-2 =0 x+3 =0
x-2+2=0+2 x+3-3=0-3
x=2 x=-3
