Answer:
12 yards and 1 foot
Step-by-step explanation:
x=7y+10
x−7y=10
x−7y+7y=10+7y
x=−7y+21/2
12/2 is a fraction
2x+14y=21
2x+14y+−14y=21+−14y
2x=−14y+21
2x2=−14y+21/2
y==(x+2)²-4
y=x²+4x
=(x+2)²-4
(x+2)²==x²+4x+4
a/3 = b/2
a/b = 2/3
I guess you wanna know a:b
So it's 2:3
4.R=16
D=16+16=32
C=
C=32π
then do the same thing for other problem
