What one do you need help with?
Answer:
a^2 + b^2 = c^2, where c is the hypotenus and a and b are the legs
Step-by-step explanation:
23x-13=2(x+2)
First you would distribute the 2 into the parenthesis
It will look like this after: 23x-13=2x+4
Then you would subtract 2x on both sides because u have to get the x's on one side
It will look like this after:21x-13=4
Then you would add 13 to both sides
It will look like this after: 21x=17
Then you would divide 21 on both sides
Your final product is 21/17
Answer:
3x + 21
Step-by-step explanation:
3(x + 7) Distribute
3x + 21
