Answer is D
use the factor method to get the answer
x^2-36=0
x^2-6^2=0
(x-6)(x+6)=0
x=6 or -6
Answer:
A=49 B=41
Step-by-step explanation:
First, find the angle next to 88 by subtracting it from 180 to get 92.Then add that to 39 to get 131. Then subtract that from 180 to get the missing angle for A.Then add that angle to 90 to solve for the bigger triangle's missing angle, or B. Once you get that value, which is 139, subtract that from 180 to get the value for angle B.
Answer:
Step-by-step explanation:
Our Sample size is 42 rocks total. If we want to pick one red rock out of the 42, we first have to determine the possibility of doing that from the numbeer of red rocks we have total. There are 6 red rocks, so the probability of picking one of those is
6/42 or 1/7
There are 14 blue rocks. So the probability of picking one of those is
14/42 or 1/3
There are 22 white rocks. So the probability of picking one of those is
22/42 or 11/21
Answer: x= -21/10
Step-by-step explanation:
Use distributive property and combine like terms to solve.
