Area=(x-5) (x-3)
Area = x^2 -8x+15
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Area of a rectangle = width x length
The original length and width was x, so if the stage needs to be 5 feet narrower and 3 feet shorter.
x-5
x-5
The formula is:
A=(x-5) (x-3)
Solving:
A = (x.x) + (x.-3) + (-5.x)+ (-5.-3)
A = x^2 -3x -5x+15
A = x^2 -8x+15
Answer:
Kelsey must produce 34 more pendants.
Step-by-step explanation:
Giving the following information:
Fixed costs= $200
Unitary variable cost= $7.8
Selling price per unit= $13.5
Desired profit= $50
<u>To determine the number of units to be sold, we need to use the break-even point in units formula.</u>
Break-even point in units= (fixed costs + desired profit) / contribution margin per unit
Break-even point in units= (200 + 50) / (13.5 - 7.8)
Break-even point in units= 250/5.7
Break-even point in units= 43.86 = 44
Kelsey must produce 34 more pendants.

Answer:
Please Find the solution below
Step-by-step explanation:
Let us say the two equations are
x+y=5 --------------(A)
x-y=1 -------------(B)
Let us solve them for x and y by adding them
2x=6
x=3
Hence from (A)
3+y=5
y=2
Hence our solution is
x=3, y=2
Adding same number to equation (A) say 2 we get
x+y+2=5+2
x+y=5+2-2
x+y=5
Hence equation remains the same while adding same number to each side.
Same thing happens if we add same number to equation (B)
Hence we draw the conclusion that the solution remains the same if same number is added to each side of the original equation.
