Step-by-step explanation:
lets take a look....
In order to find the perimeter of a triangle you have to get the sum of all sides. In other words,
Blue triangle:

Red triangle:

Difference:

Convert to improper fraction: 2 5/12 = 29/12
Divide 29 by 12: 29/12 = 2.42
2.42 inches

9 cm
Step-by-step explanation:
![\sqrt[3]{729}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B729%7D)
![=\sqrt[3]{9*9*9}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B3%5D%7B9%2A9%2A9%7D)

Answer:
Option B is correct.
Step-by-step explanation:
Recall that the domain is the set of (unique) inputs and the range is the set of outputs (which do not have to be unique).
The set of inputs of the given relation is {-1, 9, -10, 1}, and this set is also found in Option B. The set out outputs is {7, 2, 6, -6|, which is in Option B.
Answer:
20cm
Step-by-step explanation:
Given data
Area= 80cm^2
we know that the expression for the area of a triangle is
A= 1/2B*H
from the given expression 1/2(8h) =80 the base is 8cm
let us substitute to find the height h
1/2(8h) =80
4h=80
h= 80/4
h= 20cm
Hence the heigth h is 20cm
