7x+14=6x+30 is the answer
Convert the cm to feet for the base and the height:
12/2 = 6 x 3 = 18 feet
9/2 = 4.5 x 3 = 13.5 feet
area = 1/2 x base x height
Area = 1/2 x 18 x 13.5
Area = 121.5 square feet
answer: 121.5 square feet
Answer:
Step-by-step explanation:
we have
Solve for a
That means ----> Isolate the variable a
Factor 3 in the numerator right side
Simplify right side
subtract a both sides
subtract 1 both sides
Rewrite
I get the base to be 4.74 and the height to be 12.74
