The quadratic equation is in factored form, which is f(x) = (x - a)(x - b), where a and b are the x-values for the x-intercepts.

The x-values for the x-intercepts are 4 and -2. We know that the y-value at any x-intercept must be 0 (otherwise it isn't an x-intercept).

Thus, either the points (4,0) or (-2,0) must be your answer (the question is only asking for one x-intercept).

Answer:

A=35, B=55, and C=25

Step-by-step explanation:

Angle A and the angle next to it are linear pairs, so you can subtract 145 from 180.

if you already know Angle A, and that the other angle is 90 degress, you can add 90+35 and subtract it from 180 to get Angle B

Angle C is paired with the angle across from it (I forgot what the term is called) so it is 25 degrees.

For this case we have that the weight of the bouquet of flowers will be:
 4.3 * 10 ^ 4 - 2 * (7.5 * 10 ^ 2)
 Rewriting we have:
 4.1 * 10 ^ 4 miligrams
 Thus, we have that the values of p and q are given by:
 p = 4.1
 q = 4
 Answer:
 
4.1 * 10 ^ 4 miligrams
 
p = 4.1
 
q = 4
