Answer:

Step-by-step explanation:
see the attached figure , to better understand the problem
we have

where
A(b) ---> is the trapezoid's area
b ---> is the other base value
Solve the equation for b
That means ----> isolate the variable b
Divide 12 by 2 right side

Divide by 6 both sides

subtract 9 both sides

Rewrite

Convert to function notation

Given:
Dimensions of a rectangular prism are 6 meters by 3 meters by 12 meters.
To find:
The surface area of the prism.
Solution:
The surface area of a rectangular prism is:

Where, l is length, b is breadth and h is height.
Putting
, we get




Therefore, the surface area of the prism is 252 square meters.
Answer:
-243v^5
Step-by-step explanation:
(-3v)^5
= (-3)^5 * v^5
= (-3 * -3 * -3 *-3 * -3)* v^5
= -243v^5
Answer:
X=0

Answer:
17.4 cm²
Step-by-step explanation:
base = 3x2.6x0.5 = 3.9 cm²
3 sides = 3(3)(3)(0.5) = 13.5 cm²
13.5 + 3.9 = 17.4 cm²
