Answer:
Approx: 2.65units
Step-by-step explanation:
Answer:
The answer is 148.6666667
Step-by-step explanation:
1) Set a linear quation

2) Cross multiply

3) Multiple the right side

4) Divide both side by 15

5) Solve the linear equation

81.56+n-2.55=0
81.56+n=2.55
n=2.55-81.56
n=-79.01
3ab...when a = 2 and b = 3
(3)(2)(3) = 6(3) = 18
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.
