Answer:
14
Step-by-step explanation:
(9x + 10)° = 136°
9x + 10 = 136
9x = 126
x = 14
When factoring find 2 numbers that when added together equal the middle value and when multiplied equal the last value.
min this problem the middle value is 7 and the last value is 10
5 + 2 = 7 and 5 x 2 = 10
The answer is: (x+2)(x+5)
Answer:
it should be 17.9, I don't really know how to explain it I'm sorry-
162.15 is the answer because you have to multiply 0.15•141 then add 21.15 to the 141 :)
