remember a(b+c)=ab+ac
8(y+4)=8(y)+8(4)=8y+32
8y+32=7y+38
minus 7y both sides
y+32=38
mius 32 oth sides
y=6
Answer:
C = 56.6
Step-by-step explanation:
Circumference Formula: C = 2πr
Simply plug in <em>r</em> into your formula
C = 2π(9)
C = 18π or 56.556
90% = 90/100 which simplifies to 9/10
It should be C. the first floor is going to be 13 feet longer, so x squared +13 is going to be the first floor
C = 3
You isolate the variable by dividing each side by factors that don’t contain the variable
