(<span>5a-5)(2a+2)
= 5a*2a -5*2a + 2*5a - 5*2
= 10a^2 - 10a + 10a - 10
= 10a^2 - 10
The product of the equation is </span>10a^2 - 10
Answer:
335.115
Step-by-step explanation:
First you find the area of the circles to do that you do pi times radius squared
For the top square do 3.14(pi)time 3²=28.26
For the middle square do 3.14 times 4.5²=63.585
For the bottom square do 3.14 times 6²=113.04
Now find the area of the entire thing do 18×12+9+6+3=18×30=540
Finally do 540-the area of the squares 28.26-63.585-113.04= 335.115
So the shaded region is 335.115
Hope this helps and have a great day!
$0.30x=y should be the answer because there is a 30cent fee for every day and x represents how many days it's kept therefore you would add 30 cents for every day it's kept so it's valid to say $0.30x=y becaue the 30 cents times the total of days it's kept = y (the toatl)
Answer:
The volume of the cylinder is 900 cubic inches
<em />
Step-by-step explanation:
Given
Let V1 represent the volume of a cone and V2 represents the volume of a cylinder
Required
Determine the volume of a cylinder with same dimension
The volume of a cone is calculated as:
The volume of a cylinder is calculated as:
Since, the cone and cylinder have the same dimensions, we can substitute 
for 
in
So, we have:
Multiply both sides by 3
Substitute 
for 
<em>Hence, the volume of the cylinder is 900 cubic inches</em>
The answer is 5/24
I hope that helped!^o^
