Which statements describe the graph of y = 4x2 + 28x + 49? Check all that apply.

The graph has two x-intercepts because 4x2 + 28x + 49 has two different factors.
The equation 2x + 7 = 0 can be used to find a zero of the function.
The equation (2x – 7)2 = 0 can be used to find the y-intercept.
The graph has a double root at x = StartFraction negative 7 Over 2 EndFraction.
The graph intersects the y-axis at y = 49.

answer: '

the distance between points l and m

step-by-step explanation:

we can set up an equation to find the girls' ages. the equation is         28=0.5x-5+x. (comment if you need me to explain how i got this equation.) so, you add x and 0.5x to get 1.5x and add 5 to each side. your new equation is 33=1.5x. now divide both sides of the equation by 1.5 to get 22=x. because x is mary's age, to find jasmine's age we subtract mary's age from 28. we find that mary is 22 years old and jasmine is 6 years old.

i think the answer is d.
