I got 3.825
your equation would be
(2x-1)(x+7)=72
when you distribute youd get
2x^2 +13x -7 =72
move the 72 over giving you
2x^2 +13x -79=0
i used the quadratic formula and the answer would be 3.825 because a negative answer wouldn’t make sense in this situation
First, replace all variables with the given values.
12(9) + 9(2) + 2(12)
This should then equal 150, then the formula says to multiply this answer by 2. Doing so, should give a final answer of 300.
So First of all we need to know how to find the area of a circle.
Assuming that the apple pie is the shape of a circle
The formula for area is

Well we know that the radius = 3.14
And we know that
= 3.14 as well.
All we have to do is multiply..
3.14 x
= 30.95
So the area of the pie is 30.95 in
Good Luck! :)
