I actually just learned this in 8th grade and it was so easy its crazy but its honestly simple it helps you solve the triangles and things and the equation is a squared + b squared = c squared and the a and b you would plug in the sides of the triangle or whatever shape your working with and square those numbers then find c by adding the two and then you square the c at the end and that will be your answer.
Answer:
W=A/L
Step-by-step explanation:
If the area of the rectangle is L*W, you can just rearrange the equation A=L*W to get W=A/L, an equivalent equation.
Answer :he can fill 5 bags
Step-by-step explanation: 3/4 times 5
This is the start to the approach that would be taken to get both variables in terms of only one so it can be solved but since the numbers are so small you could easily test out numbers and figure out that it's 6 and 10 feet.
length = width + 4
length * width = 60
(width + 4) * width = 60
Y=5x+2 is the line for neither parallel nor perpendicular
