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

Answer:
All angles in a triangle sum up to 180 degrees.
So, 63+71+x=180 degrees.
You add like terms: 134, and then add x.
134+x=180 degrees.
Minus x from both sides.
180-134=x.
What do you think x is?
B. -2/9
flip the -3 and make it 1/3 and then multiply
