A. (3x-2)^2
B. 5x-4y
5x=4y
Step-by-step explanation:
Answer:
He can run 12 miles in 132 minutes.
Step-by-step explanation:
2/22=x/132
simplify 2/22 into 1/11
1/11=x/132
cross product
11*x=1*132
11x=132
x=12
Factor
36-n^2 is difference of 2 perfect squares
a^2-b^2=(a-b)(a+b)
6^2-n^2=(6-n)(6+n)
factor
n^2+16n+60
find what 2 numbers multiply to 60 and add to 16
factors of 60=2,2,3,5
the numbers are 10 and 6
so factored out
(x+6)(x+10)
(x+6)=(6+x)
so the equation is
[(x+6)(x+10)]/[(6+x)(6-x)]=[(6+x)/(6+x)] times (x+10)/((6-x)=1 times (x+10)/(6-x)
the answer is (x+10)/(6-x)
V = value
t = time ( number of years)
so V=1045 - 95t
to find the number of years to reach 0
0=1045-95t
1045=95t
t=11 years
