Answer:
9
Step-by-step explanation:
m = j^2 -7p
18 = j^2 -7(9)
18 = j^2 - 63
81 = j^2
√81 = √j^2
9 = j
Answer:
x=3
Step-by-step explanation:
The altitude to the hypotenuse of a right triangle is the mean proportional between the segments into which it divides the hypotenuse ⇒<span>
</span>altitude = √(9*3) = √27
<span>By the Pythagorean theorem:
y = </span>√(9² + (√27)²) = √(81+27) = √108 = 6√3 ← answer
