Answer:
5 yd
Step-by-step explanation:
Use Pythagorean theorem,
Hypotenuse² = base² + altitude²
= 3² + 4²
= 9 + 16
= 25
Hypotenuse = √25 = √5*5 = 5 yd
Move x
5y = - 15 - 3x
y = - 3 - 3/5x
y = - 3/5 - 3
-y = 3/5 + 3
The irrational number would be square root 15
Distributive property states a(b+c) = ab + ac
9(10 + x) = 90 + 9x
Your answer is B. 90 + 9x.
