Answer:
10v^2
Step-by-step explanation:
(I'm assuming the 2's are all exponents)
3v^2 - 2v^2 + 9v^2 <- think of it as 3 - 2 + 9 = 10, then add the rest back on
10v^2
Answer:
B. 20
Step-by-step explanation:
64 ÷ 8 + 6(2)
64 ÷ 8 + 12
8 + 12
20
AB = √(8^2 + 6^2)
AB = √100
AB = 10
AC = √(8^2 + 15^2)
AC = √289
AC = 17
BC = 9
P= AB + AC + BC
P = 10 + 17 + 9
P = 36 units
34)
Area of ABC = 1/2 x 8 x 9
A = 36 square units
