A rectangle is 12 cm longer than it is wide. If its length and width are both decreased by 2 cm, its area is decreased by 108 cm². Find its original dimensions.
Let the width be "x" cm.
Then the length is "x+12" cm
And the area = x(x+12) = x^2+12x cm^2
----------------------------
Change the dimensions:
width = "x-2" cm
length = "x+10" cm
New area = (x-2)(x+10) = x^2 + 8x - 20 cm^2
------------------
Equations :
Old area - New area = 108 cm^2
x^2+12x -(x^2 + 8x - 20) = 108
4x + 20 = 108
4x = 88
x = 22 cm (original width)
x+12 = 24 cm (original length)

x = -2
y = 3
[tex]-4x-2y=2\\ -4x+y=11[/tex]
Subtract the two equations
[tex]-4x-2y-(-4x+y)=2-11[/tex]
Remove parentheses
[tex]-4x-2y+4x-y=2-11[/tex]
Cancel one variable
[tex]-2y-y=2-11[/tex]
Combine like terms
[tex]-3y=2-11[/tex]
Calculate the sum or difference
[tex]-3y=-9[/tex]
Divide both sides of the equation by the coefficient of variable
[tex]y=\frac{-9}{-3}[/tex]
Determine the sign for multiplication or division
[tex]y=\frac{9}{3}[/tex]
Cross out the common factor
[tex]y=3[/tex]
Substitute into one of the equations
[tex]-4x+3=11[/tex]
Rearrange variables to the left side of the equation
[tex]-4x=11-3[/tex]
Calculate the sum or difference
[tex]-4x=8[/tex]
Divide both sides of the equation by the coefficient of variable
[tex]x=-\frac{8}{4}[/tex]
Cross out the common factor
[tex]x=-2[/tex]
The solution of the system is
[tex]x=-2\\ y=3[/tex]

A rectangular parking lot is 120 feet long and 75 feet wide. Diego made another scale drawing of the parking lot at a scale of 1 to 180. The drawing he produced is also 8 inches by 5 inches. (Remember the video. Scales with no units represent the SAME UNIT. So how is Diego using a different scale than Lin, but ended up with the same drawing?) (12 inches = 1 foot) 2.) Explain or show how Diego's scale would produce an 8 inch by 5-inch drawing.
Answer:
We kindly invite you to read carefully the explanation detailed below for further details.
Step-by-step explanation:
At first we understand that Diego converted length and wide units from feet to inches ([tex]1\,ft = 12\,in[/tex]) and then he divided each term by 180, since he was using a reduction scale, so that rectangular parking lot can be represented on paper. That is:
Step 1 - Unit conversion:
[tex]l = 120\,ft[/tex] ([tex]l[/tex] - Length)
[tex]l = 120\,ft\times \frac{12\,in}{1\,ft}[/tex]
[tex]l = 1440\,in[/tex]
[tex]w = 75\,ft[/tex] ([tex]w[/tex] - Width)
[tex]w = 75\,ft\times \frac{12\,in}{1\,ft}[/tex]
[tex]w = 900\,in[/tex]
Step 2 - Applying scaling:
[tex]l' = \frac{l}{180}[/tex] ([tex]l'[/tex] - Scaled length)
[tex]l' = \frac{1440\,in}{180}[/tex]
[tex]l' = 8\,in[/tex]
[tex]w' = \frac{w}{180}[/tex] ([tex]w'[/tex] - Scaled width)
[tex]w' = \frac{900\,in}{180}[/tex]
[tex]w' = 5\,in[/tex]

Solve for x, I'm confused
[tex][Hello,BrainlyUser][/tex]
Answer:
x = 22
Step-by-step explanation:
Knowing that it a supplementary angle = 180 degree
It a right angle therefore it makes that 90 degree
Thus,
The 2 equation is
4x + 2 = 90
3x + 24 = 90
Let first solve this one
4x + 2 = 90
Subtract 2 from both sides
4x + 2 - 2= 90-2
Simplify
4x = 88
Divide both sides by the same factor
4x/4 = 88/4
Simplify
x = 22
Now the second equation:
3x + 24 = 90
Subtract 24 from both sides
3x + 24 - 24 = 90 -24
Simplify
3x = 66
Divide both sides by the same factor
3x/3 = 66/3
Simplify
x = 22
Hence, x = 22.

witcch point lies on the line of the point-slpoe equation y-2=5(x-6)
Answer:
See below.
Step-by-step explanation:
Simplify
y - 2 = 5(x - 6)
y - 2 = 5x - 30
y = 5x - 28
Points which lie on the line
(6, 2)
(5, -3)
(7, 7)
Answer:
(6, 2 )
Step-by-step explanation:
the equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
y - 2 = 5(x - 6) ← is in point- slope form
with (a, b ) = (6, 2 )
then (6, 2 ) is a point on the line

4.a. 7.2
b. 2.4
5.a. 104

18 x 5 = 90 (100%)
18 x 2 = 36
18/4 = 4.5
14.4/2 = 7.2
7.2/3 = 2.4
52 x 2 = 104 (100%)
(195/3) 4 = 65 x 4

#6 find the slope in the graph MULTIPLE CHOICE
I'm assuming problem 6 is the graph on the right.
If so, then the slope is 1/2
Start at a point like (0,-1) which is the y intercept. Move up 1 and to the right 2 to arrive at (2,0) which is the x intercept.
The movement pattern "up 1, right 2" determines the slope directly
slope = rise/run = 1/2
rise = 1 = go up 1
run = 2 = go to the right 2
------------------------------
You could also pick two points from the blue line, then use the slope formula. If we picked (0,-1) and (2,0), then
m = (y2-y1)/(x2-x1)
m = (0-(-1))/(2-0)
m = (0+1)/(2-0)
m = 1/2
please help I'm so confused.

Tim sold 15 boxes of doughnuts for a school fundraiser. The boxes cost $4 each. Which pair of expressions shows two ways to determine the total cost of the doughnuts Tim sold? A) 10 × 4 and 10 × 5 B) 15 × 4 and 10 × 4 C) (15 × 4) + (5 × 4) and 4 + 4 + 4 + 4 D) (10 × 4) + (5 × 4) and 15 + 15 + 15 + 15
Answer:
(D) (10 × 4) + (5 × 4) and 15 + 15 + 15 + 15
Step-by-step explanation:
Given;
total number of boxes of doughnuts sold, T = 15 boxes
the cost of each box of doughnuts, C = $4
The total cost of the doughnuts sold = 4 x 15 = $60
The only option that contains pair of expressions that is equal to $60 is option D.
(D) (10 × 4) + (5 × 4) and 15 + 15 + 15 + 15
(10 × 4) + (5 × 4) = 40 + 20 = $60
15 + 15 + 15 + 15 = $60
Mr. Rahm purchases a new car for $24,000 and finances it with a 5-year simple interest loan at an annual rate of 3. 75%. What are Mr. Rahim's monthly car payments?
Answer:
$475
Step-by-step explanation:
The total amount Rahim will be paying is found from the simple interest formula ...
A = P(1 +rt) . . . . . P is the loan amount, r is the annual rate, t is the number of years.
A = $24,000(1 +0.0375×5) = $28,500
Spread over 60 monthly payments, that amounts to ...
$28,500/60 = $475 . . . per month
__
Additional comment
Mr. Rahim's loan has an APR of 6.98%. This sort of loan costs more than the interest rate might suggest, because interest is still being paid on principal that has already been repaid.
What is the answer to this?
Answer:
its c
Step-by-step explanation:
A x B = ab
A x C = ac
A x D = ad
