Answer:
4x + 1
Step-by-step explanation:
note that (f + g)(x) = f(x) + g(x) , thus
f(x) + g(x)
= x + 3x + 1 ← collect like terms
= 4x + 1
multiply 40 by 30% to find the discount then subtract
40 * 0.30 = 12
40-12 = 28
they would cost $28
Answer:
2a+8
Step-by-step explanation:
12 because the rest of the numbers are all similar except 12
Like terms: in the case of exponents, the same exponents for different numbers
Like 7x and 8x are like terms.
5x and 6x^2 would be unlike terms
Get it??
Good luck~~
