<span>C. (1,0)
This is a simple matter of determining the midpoint of both diagonals. The 1st diagonal is from point H(-2,2) to point J(4,-2). And the midpoint is simply the average of both points. So you get:
((-2+4)/2, (2-2)/2) = (2/2, 0/2) = (1, 0)
And the 2nd diagonal is from point I(4,3) to point K(-2,-3). And its midpoint is
((4-2)/2, (3-3)/2) = (2/2, 0/2) = (1, 0)
So you see that the midpoint of both diagonals is the same (1,0) and that matches option C.</span>
Answer:
r = 9
Step-by-step explanation:
Given
r + 3 = 3(r - 5) ← distribute
r + 3 = 3r - 15 ( subtract r from both sides )
3 = 2r - 15 ( add 15 to both sides )
18 = 2r ( divide both sides by 2 )
9 = r
Answer:
560m³
Step-by-step explanation:
Cuboid : length = 16, width = 5, height = 4
Prism : base = 16, perpendicular height = 6, height = 5
V = volume cuboid + volume prism
V = 16 x 5 x 4 + (16 x 6 : 2 x 5) = 560m³
Correct answer is C 104
