-mnp(3m - 5n + 7p) =
-3m^2np + 5mn^2p - 7mnp^2 <==
2×+y=0,
×-y=6
Add the 1st to the 2nd equation==> 3x +y-y=6+0==> 3x=6 & x=2
Plug 2 into any of the equation & you will get y=-4
Answer:
351.658 square in
Step-by-step explanation:
First find the circumference of the circle
C = 25.13
Find area of the circle
A = 50.27
Multiply the circumference by the height
25.13 × 10 = 251.3
Add 251.3 with 50.27 twice
251.13 + 50.27 + 50.27 ≈ 351.658
Therefore your answer is D) 351.658 square in
That would be a right-angled triangle.
