You work 50 -40 = 10 extra hours per week but get paid for 1.5 times that, or 15 extra hours. In all, you're paid for 40 +15 = 55 hours per week.
.. (55 h/wk)*(4 wk/mo)*($16/h) = $3520/mo
Your gross pay for the month (4 weeks) will be $3,520.
Here is one way to solve for x.
Step 1) 2x^2-7=9
Step 2) 2x^2-7+7=9+7
Step 3) 2x^2=16
Step 4) (2x^2)/2=16/2
Step 5) x^2=8
Step 6) sqrt(x^2)=sqrt(8)
Step 7) |x|=sqrt(8)
Step 8) x=sqrt(8) or x=-sqrt(8)
-------------------------------------
Below are explanations/reasons to each of the steps above.
Step 1) Original equation
Step 2) Add 7 to both sides
Step 3) Combine like terms
Step 4) Divide both sides by 2
Step 5) Simplify
Step 6) Apply the square root to both sides. The notation "sqrt" is shorthand for "square root"
Step 7) Use the rule that sqrt(x^2) = |x| for all real numbers x
Step 8) Use the rule that if |x| = k then x = k or x = -k for some fixed number k.
-------------------------------------
The two solutions are
x = sqrt(8) or x = -sqrt(8)
3,045 = 210x
3,045/210 = 14.5
A good estimate of the cost would be:
$14.50
Answer:
The area is equal to 
Step-by-step explanation:
we have
A(0, 0), B(2, -2), C(0, -4), D(-2, -2)
Plot the figure
The figure is a square (remember that a regular polygon has equal sides and equal internal angles)
see the attached figure
The area of the square is
<u><em>Find the distance AB</em></u>
the formula to calculate the distance between two points is equal to
substitute the values
<u><em>Find the area of the square</em></u>
