From the given attachment, the triangles are similar.
45/(6x + 4) = 90/(4x + 56)
45(4x + 56) = 90(6x + 4)
180(x + 14) = 180(3x + 2)
3x - x = 14 - 2
2x = 12
x = 12/2 = 6
Length of midsegment = 6x + 4 = 6(6) + 4 = 36 + 4 = 40
81, an=-12+((32)-1)3
32-1=31 times 3=93-12=81
Answer: C) 297 in2
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Surface area of a square pyramid (S) = 2 (length of the base) slant + length of the base ^2
S = 2bs + b^2
Replacing with the values given:
S = 2 (9) 12 + 9^2
S = 216 +81 = 297 square inches
Feel free to ask for more if needed or if you did not understand something.
They split it 50/50 that's the answer
