a
7
because 4a + 7 - 7
35 - 7
equals 4a
28
and 4a/4
28/4
equals a
7
Part A:
To get the interest of 1 year
Multiply 20,000 by 5% or 0.05
You get $1,000
Thats the amount for 1 year, now to get for 4 years, multiply 1,000, by 4
She pays $4,000 in interest
Part B:
If she pays it off in 2 years, instead of 4 years, she will pay an interest of $2,000, divide 4 by 2
Part C:
This is the same as part b, she saves $2,000
Hope this helps

The answer to your question is 77 because the formula for area for a triangle is A=1/2BH and the base is 11 feet and the height is 14 feet. So, (14•11)/2 is 77. Therefore, 77 squared feet is the answer.
