4)-9=r/4
r=-9×4=-36
answer is D
5)-9=3/8n
n=-9×3/8
n=-24
answer is A, I guess, because there are two = signs, so perhaps this is a mistake and there should be - instead of =

Step-by-step explanation:
Answer:
Step-by-step explanation:
a² + b² = c²
side1² + side2² = hypotenuse² side 1 = 6.75 hypotenuse = 11.25
solve for side 2 = ???
side2² = hypotenuse² - side1²
side2 =
= √(11.25² - 6.75²)
= √(126.56 - 45.56)
= √(81)
side 2 = 9
