(a^3b)^2 • 4ab^3
a^6b • 4ab^3
4a^6b+1b^3
(b1+b2)h+PH is the formula for surface area of a trapezoidal prism
Answer:
In the given expression 
Variables = m, r
Coefficients = 7, 6 and -3
constant= -8
Step-by-step explanation:
We are given the expression 
We need to give variable, coefficients and constant.
Variable: The value of variable may change. It can be represented by x, y or any other letter
Coefficients: A numerical or constant quality that is placed with the variable. For example in 4x, 4 is coefficient
Constant: It is fixed value. It cannot be changed.
So, in the given expression 
Variables = m, r
Coefficients = 7, 6 and -3
constant= -8
?=118°
Answer:
<6+62=180 co interior angle
<6=180-62=118°
