Large rectangles = 2*3*6
medium rectangles = 2*2*6
small rectangles = 2*2*3
surface area = 72 cm^2
Answer:

Step-by-step explanation:
Consider the options for this question are as follow,
Here, In triangles ABC and PQR,
AB = c, BC = a, AC = b, PQ = r, QR = p and PR = q,
Since,

We know that,
The corresponding sides of similar triangles are in same proportion,
Thus,




Answer:
39
Step-by-step explanation:
g(x)= -2x+2 and f(x)= 3x^2+4
(g+f)(-3)
g(-3) = -2(-3) +2 = 6+2 =8
f(-3) = 3 (-3)^2 +4 = 3(9)+4 = 27+4 = 31
(g+f)(-3) = g(-3) + f(-3) = 8+31 = 39
Answer:
3rd one
Step-by-step explanation:
12
The answer is 15h² + 26h - 21
<span>(5h – 3)(3h + 7) = 5h * 3h + 5h * 7 - 3 * 3h - 3 * 7 =
= 15h</span>² + 35h - 9h - 21 =
= 15h² + 26h - 21
