Answer:
6
Step-by-step explanation:
4 1/2 = 9/2=18/4
(18/4)/(3/4)=18/3=6
so she need 6 bags
Using the Pythagorean Theorem, the height of the equilateral triangle is given by:
A. inches.
<h3>What is the Pythagorean Theorem?</h3>
The Pythagorean Theorem relates the length of the legs and of a right triangle with the length of the hypotenuse h, according to the following equation:
For this problem, we have that:
- The height is one side of the triangle.
- The other side is half the length, of 7 in.
- The hypotenuse is the length, of 14 in.
Hence the height is found as follows:
inches.

Add all sides.
5x+2+3x+8+4x-1
Combine like terms
12x+9
Subtract nine to get it on the other side of the equal sign
12x= -9
Divide by twelve
x=-9/12
Simplify
x=-3/4
Plug in x.
Answer:
I could be wrong, but I think it's x=12
