Answer:
10 yards 2 inches
Step-by-step explanation:
15 yd 5 in - 5 yd 3 in =
10 yards and 2 inches
Hi there!

13y² + 10y - 3 = 5y²
Begin by moving all terms to one side:
13y² + 10y - 3 - 5y² = 0
Combine like terms:
8y² + 10y - 3 = 0
Factor using the guess-and-check method.
(4y - 1)(2y + 3) = 0
Set each factor equal to 0 to find the solutions:
4y - 1 = 0
4y = 1
y = 1/4
2y + 3 = 0
2y = -3
y = -3/2
31.7 is the answer. Do you need any explanation?
x = 0, x =
, x = - 
since we have a product of factors equal to zero, equate each factor to zero and solve for x
x² = 0 ⇒ x = 0 ( multiplicity 2 )
5x - 7 = 0 ⇒ x = 
3x + 2 = 0 ⇒ x = -
