Answer:
6m + 3n.
Step-by-step explanation:
The area of a trapezoid = h/2 (a + b), where h = altitude and a and b are the lengths of the opposite parallel sides.
So here:
h = 6, a = m and b = m+n.
So area = 6/2(m + m + n)
= 6/2(2m + n)
= 3(2m + n)
= 6m + 3n.
498+345 is the answer but you divide the 3 for base of 9
The answer to this problem would be B. Here are the steps:
So, the dimensions of the prism are: 9,3, and 7.
Multiply them all: 9×3×7=189
Lastly: you multiply 189×1/3=63 yd^3
Incase you are wondering, since each cube is 1/3 in length you multiply that by the volume of the prism.
Hope this helps (:
Answer:
D. QR > PR > PQ
Step-by-step explanation:
The side length of the triangle is proportional to angle measures so we need to determine the angle measure first:
Angle P = 99
Angle Q = 41
Angle K = 40 so now the longest side length would be the one that sees biggest angle, angle P.
QR > PR > PQ
