Answer:

x^2 +3x -504

Step-by-step explanation:

Sort of do what you'd do to solve but in reverse. You need 21 for a zero, so the binomial factor would be (x-21) since if you set that = to zero you'd get 21. Same for -24. The binomial factor would be (x+24) since that would give you -24. Now that you have the two binomials, you can just multiply them and get the quadratic. :)

Answer:

E. x² + 11x - 42 = 0

Step-by-step explanation:

let the square sides be x

A = bh = (x + 3 + 3)(x + 2 + 3) = 72

(x + 6)(x + 5) = 72

x² + 11x + 30 = 72

x² + 11x - 42 = 0

What are the zeros of the function graph the function. <br> y=x(x+5)(x+4)

SIZIF [17.4K]

<span>Zeroes are found by setting y = 0.

x(x+5)(x+4) = 0
>> x=0 OR x+5=0 OR x+4 = 0
>> x = 0, x = -5, x = -4

So the zeroes of this function are x = 0, -5, -4/

For the graph, check attached image file.</span>

I have no idea what to do, help :’)

Ksenya-84 [330]

Answer:

x = 52

Step-by-step explanation:

I have included a chart to identify which angles are congruent (only alternate exterior/interior and corresponding). Basically if they are not alternate exterior/interior or corresponding, then they add up to = 180 degrees.

So since these angles are same side interior, they add up to = 180 degrees. We can write this as: A + B = 180

A + B = 180

2x + 76 = 180

2x = 104

x = 52

I hope this helps!
