the theory is ab=cd where the lines across form eachother are a and b and the other two lines are a and d
a=7
b=n+4
c=5
d=n+8
7(n+4)=5(n+8)
7n+28=5n+40
2n+28=40
2n=12
n=6
C(x)=125x+75
You multiply 125 by how many family members and and the 75
Answer:
20 schools(D)
Step-by-step explanation:
Answer:
2,799 square cm
Step-by-step explanation:
Volume of cone: (1/3)π(9^2)(40)=1,080π
Volume of cylinder: π(3^2)(21)=189π
1,080π - 189π = 891π = 2799.2 square cm
