we multiply 90 by 1 then over 5
1 quarter, 2 dimes, 2 nickels, 10 pennies
Answer:
It's impossible because the figure is greater than 10
Step-by-step explanation:

Therefore:

This seems like a right triangle problem.
So assuming 14 feet is the hypotenuse and 4 feet is a leg of the right triangle, we can use the pythagorean theorem (
) to solve for the height of the house, in which we shall name it x.
So, the equation is
.
Solve for x:
16+x^{2}= 196
x^{2}= 196-16
x^{2}= 180
x = 6√5 feet
