She should try to collect 75 each week
Answer:
90%
Step-by-step explanation:
Is means equals and of means multiply
135 = P * 150
Divide each side by 150
135/150 = 150P/150
.9 =P
Change this to percent form by multiplying by 100%
.9*100%
90%
L=6+W
A=LW
sub 6+W for L
A=(6+W)(W)
expand
oh, A=50
50=W²+6W
minus 50 both sides
0=W²+6W-50
we gots to use quadratic formula
for
aW²+bW+c=0
W=

we got
a=1
b=6
c=-50
W=

W=

W=

W=

W=

W=

or W=

aprox
W=-10.6811 or W=4.68115
can't be negative width
width=4.68115 or -3√59
