Answer:
-15, -17
Step-by-step explanation:
x^2 + 32x = –255 move the -255 to the left
x^2 + 32x +255=0
What two number when multiplied equal 255? Those same two numbers when added make 32. 17*15 make 255 and added is 32
(x+15)(x+17) For x+15=0 move the 15 to the other side. x= -15. Same with x+17=0 is x= -17
x= -15, -17
3y + 11 + 7x - 30 + 5x + 14
3y + 12x - 5
3y = -12x + 5
y = (-12x + 5)/3
x = (3y - 5)/-12
hope this helps
It would be y=x+3 because you have a slope of 1 and a y-intercept at 3
The expression that represents the density is D = h^2 - 4h + 20/pi h^2
