Answer:
B*H= 11*6= 66m
area of the figure= 132m
Step-by-step explanation:
You know that we have to simplify the algebra equation, so first you have to combine x and 2x. X + 2x equals to 3x. Now that we combined x and 2x which makes 3x, we have to do 7 and -8. 7 + -8 which equals to -1. Therefore, the answer to this algebra equation is 3x + -1.
Answer:
x=1 and y=360
you divide 720 by 2 to get the LCM
