L=2W-4
PERIMETER=2L+2W
58=2(2W-4)+2W
58=4W-8+2W
58=6W-8
6W=58+8
6W=66
W=66/6
W=11 ANS. FOR THE WIDTH.
L=2*11-4
L=22-4
L=18 ANS. FOR THE LENGTH.
PROOF:
58=2*18=2*11
58=36+22
58=58
Percent means parts out of 100
74%=74/100=0.74
'of' means multiply
so
128 is 74% of what means
128=0.74 times what
divide both sides by 0.74
172.97297297297297297297297297297=what
the number is about 173

$9.04 per hour
9514 1404 393
Answer:
b = -2ax
Step-by-step explanation:
Multiply both sides of the equation by -2a.
x = -b/(2a)
(-2a)x = b(-2a)/(-2a) = b
b = -2ax
