144, its just repeated addition... 12+12+12+12+12+12+12+12+12+12+12+12=144
First the nth term which is 6n-3
So 6x45-3 is your answer
Answer:
Step-by-step explanation:
Draw a triangle and label the sides (picture below):
● the length is 2x+2
● and the width or the height is 6x
The perimeter of a rectangle is the sum of the sides
● P = 2x+2 + 6x + 2x+2 + 6x
Isolate the similar terms
● P = (2x+2x+6x+6x) + (2+2)
● P = 16x + 4
Answer:
Area = base * height
224 = 16 * height
height = 14
The height is 14 centimeters.
Your answer is c.
