(f+g)(x) just means f(x) + g(x)

Choice B
Answer:The slope is -6/23 or 6/-23 since the negative sign can be on the numerator or denominator, or in the middle. However, you cannot have a negative sign on the numerator and denominator at the same time for negative number or it will make it positive.
Step-by-step explanation:
Delta y/Delta x=
y2-y1/x2-x1=
12-18/11-(-12)=
-6/23
Answer:
44
Step-by-step explanation:
The sum of the ratios is 6 + 2 + 3 = 11
Let b = total number of boots sold last week
If 24 football boots are sold, the equation representing this =
6/11 x b = 24
To solve for b, divide both sides by 11/6
b = 44 = total number of boots sold last week
Answer:
C: x^4+6x^3-12x-72
Step-by-step explanation:
For the function : f(x)=√x^2+12x+36
It can be factorized to
f(x)=√(x+6)²
=x+6
f(x)*g(x)
=(x+6)(x^3-12)
Expand the brackets
=x^4-12x+6x^3-72
rearrange the numbers
x^4+6x^3-12x-72
