Answer:
the first equation
Step-by-step explanation:
Let A= <span>2 – 11x2 – 8x + 6x2, the standard form of A is
A = - 5x² -8x + 2
</span>
Horizontal distance = 48'
difference in elevation = 18"-6" = 12" = 1'
Slope of the sewer line = rise/run = 1/48 = 0.0208 = 2.08%
Answer:
I'm pretty sure its 28?
Step-by-step explanation:
Divide both sides by -2
-2(2x-1)=3x+16
distribute
-4x+2=3x+16
add 4x to both sides
2=7x+16
minus 16 from both sides
-14=7x
divide both sides by 7
-2=x
