Answer: 0</h3>
The discriminant is the number under the square root of the quadratic formula

The discriminant formula is 
If D = 0, then the whole square root portion is 0 meaning we end up with the solution 
225
Step-by-step explanation:
Look it up on google.
Answer d because the y intercept is 3 and its a positive slope
Yint is where the line crosses the y axis or where x=0
set x=0
3y+4x=15
x=0
3y+4(0)=15
3y+0=15
3y=15
divide by 3
y=5
yint is (0,5) or at y=5
Answer:
We divided the figure into 1 triangle and 2 rectangles.
Adding up the area of them, we get the total area:
A = 14 x (10 + 8 + 12 - 16)/2 + 8 x 5 + 6 x (12 + 8)
= 258 (yd2)
Hope this helps!
