Answer:
4x^3+4x^2
Step-by-step explanation:
f(x) = 4x^2
g(x) = x+1
(f•g)(x) = (4x^2) *(x+1) = 4x^3+4x^2
Answer:
a. -3x = -2y
When x=6, y=9
Step-by-step explanation:
From the hanger, There are two sides
If x=triangle and y=square
First side has 1 triangle and 3 squares
It can be represented by
x+3y
Second side has 4 triangles and 1 square
It can be represented by
4x+y
Equate the first and second side
x+3y=4x+y
Collect like terms
x+3y-4x-y=0
-3x+2y=0
-3x=-2y
Find y when x=6
-3(6)=-2y
-18=-2y
Divide both sides by -2
-18/-2=-2y/-2
9=y
y=9
Answer:
b
Step-by-step explanation:
It's b because if you plug in 1 for d in each of the equations, you get 99 in b only.
Answer:
Given the equation: 
The general equation of quadratic formula for 
where a, b and c are constant;
then, the solution for this equation is given by;
......[1]
From the equation, we have
a =2, b=14 and c=16
Substitute these values in [1] to solve for x;
or
Simplify:
then,
and
Therefore, the solutions for the given equation is; x =-2 and
