Multiply: (4x^2+4x+1)by(2x^2+x-2)<br><br>no spam step by step explanation

klemol [59]

Answer:

the answer is 34

Step-by-step explanation:

first we put the equation together (4x^2+4x+1)by(2x^2+x-2)

so we multiply the formula together so we (4x^2+4x+1) (2x^2+-2) and that's how you get 34

Answer:

B) Yes, because the slope is $-\frac{25}{3}$ and the zero is (12, 0)

Step-by-step explanation:

From inspection of the graph:

y-intercept = (0, 100)
Two points: (3, 75) and (6, 50)

$\sf slope\:(m)=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{50-75}{6-3}=-\dfrac{25}{3}$

Therefore, the equation of the line in slope-intercept form y = mx + b

(where m is the slope and b is the y-intercept) is:

$y=-\dfrac{25}{3}x+100$

To find the zero (when y = 0), set the equation to zero and solve for x:

$\implies -\dfrac{25}{3}x+100=0$

$\implies \dfrac{25}{3}x=100$

$\implies 25x=300$

$\implies x=12$

Therefore, the zero is at (12, 0)

Therefore, the graph does represent the function because the slope is $-\frac{25}{3}$ and the zero is at (12, 0)
