Answer:
Th answer is x = (c - ab) / a
Step-by-step explanation:
The steps are :
a(x + b) = c
ax + ab = c
ax = c - ab
x = (c - ab) / a
Answer:
Work done 
lb-ft
Step-by-step explanation:
The density of the chain in lb/ft is equal to
lb/ft
Total Work done is equal to the summation of work done up to the top of building.
We will use integration for this evaluation.
The mathematical relation is as follows
where "p" is the density
Substituting the given values, we get
Work done lb-ft
Answer: -37 & -3
Step-by-step explanation:
-20-17= -37
-20+17= -3

Using the quadratic formula..
2.3 Solving x2+7x-4 = 0 by the Quadratic Formula .
According to the Quadratic Formula, x , the solution for Ax2+Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by :
- B ± √ B2-4AC
x = ————————
2A
In our case, A = 1
B = 7
C = -4
Accordingly, B2 - 4AC =
49 - (-16) =
65
Applying the quadratic formula :
-7 ± √ 65
x = —————
2
√ 65 , rounded to 4 decimal digits, is 8.0623
So now we are looking at:
x = ( -7 ± 8.062 ) / 2
<em> </em><em> \ /</em>
<em> Two real solutions:</em>
<em> x =(-7+√65)/2= 0.531</em>
<em> or:</em>
<em> x =(-7-√65)/2=-7.531</em>
