Answer:
x² + 8
Step-by-step explanation:
note (f - g)(x)
= f(x) - g(x)
= 2x² + 1 - (x² - 7) = 2x² + 1 - x² + 7 = x² + 8

so,
6c = 6 × 5 = 30
4b = 4 × (-3) = -12
Example:
4b - 6c
= 4(-3) - 6(5)
= -12 - 30
= - 42
4b + 6c
= 4(-3) + 6(5)
= -12 + 30
= 18
Answer:
original number is 18.07
Step-by-step explanation:
Let the original number be x
x - 17% of x = 15
x* (1 - 0.17) = 15
x * 0.83 = 15
x = 15/0.83
x = 18.072289156
Or if your wording meant 17% of a number is 15 then:
x * 17% = 15
x *0.17 = 15
x = 15/0.17 = 88.23529...
but I think you meant "decreased by 17%" so I choose x = 18.07
Add the common factors which is x plus 2x plus 4x which is 7x so now you have the bx term rewritten to 7x+8
