*just a guess*
you can combine like terms when they are using the same variables or constants. ex: you can combine 34x and 76x because of the variable
Answer:
Step-by-step explanation:
You cannot solve the problem because it doesn't have an equal sign, but I suppose you can simplify it. Look at this screenshot, it may help:
The toy is 2(x)-20, x is 100, being the toy car. So 2(100)= 200 -20 =180. The cost of the toy is $180
Answer:
4sqrt(2) cm
Step-by-step explanation:
a^2 + b^2 = c^2
4^2 + 4^2 = c^2
32 = c^2
sqrt(32) = c
c = 4sqrt(2)
