A)select the equation that has a y-intercept value of 3 A:y=(x+1)(x-3)
B: y=x^2-9
C:y=3x(x-3)
D:y=(x+1)(x+3
b) Select the equation with roots 0 and 3
A:(x+1)(x-3)=0
B:x^2-9=0
C:3x(x-3)=0
D:(x+1)(x+3)=0

its 4 because 2 times 2 is 4, if you double the number two you get four

your answer would be b

step-by-step explanation:

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
