Answer:
c = 289
Step-by-step explanation:
Given
x² + 34x
To complete the square
add ( half the coefficient of the x- term )² to x² + 34x
= x² + 2(17)x + 17²
= x² + 34x + 289 ( with c = 289 )
= (x + 17)² ← perfect square
Answer:
-X=9
Step-by-step explanation:
f(x)=-x-1
Plug in -10
-10=-x-1
add 1 to -10
-9=-x
which means -x=-9
to check, plug everything in
-10=-9-1
-10=-10

In the given question, the contractor receives a payment of 1480.00. Then he has to pay for labours and materials and this amounts to 1111.74. On the remaining amount the contractor has to deduct 18% as overhead cost.
Then the amount of money left after the labour payments = 1480 - 1111.74
= 368.26
Now the overhead cost of 18% needs to be found from the amount of money left.
Then the overhead cost = 368.26 * 18/100
= 66.28
So the labour ost takes away 1111.74 and the overhead cost takes out 66.28 from the total payment of 1480.
Then the amount of profit made by the contractor = 368.26 - 66.28
= 301.98
So the contractor makes a profit of 301.98
