Answer:
The length can be 5 and the width 10.
Step-by-step explanation:
perimeter is equal to 2L + 2W
area is equal to L * W
you get 2 equations:
30 = 2L + 2W
50 = L*W
we'll solve by substitution.
you can use either equation to solve for either variable.
we'll use the second equation to solve for L.
second equation is:
50 = L*W
divide both sides of this equation by W to get:
L = 50/W
we now have a value of L that we can substitute in the first equation which we can then use to solve for W.
the first equation is:
30 = 2L + 2W
replace L with 50/W to get:
30 = 2*(50/W) + 2W
simplify to get:
30 = 100/W + 2W
multiply both sides of this equation by W to get:
30W = 100 + 2W^2
subtract 30W from both sides of this equation to get:
2W^2 - 30W + 100 = 0
factor this equation to get:
(2W - 20) * (W - 5) = 0
solve for W to get:
W = 10 or W = 5
if W = 10, then use the equation of 50 = L*W to get L = 5
if W = 5, then use the equation of 50 = L*W to get L = 10
you have 2 possible solutions.
L = 5 and W = 10 or:
L = 10 and W = 5
both are plausible so we'll test them both out.
when L = 5 and W = 10:
the first equation becomes 2*5 + 2*10 = 10 + 20 = 30
the second equation becomes 5*10 = 50
both equations confirm that the solution of L = 5 and W = 10 is good.
when L = 10 andW = 5:
the first equation becomes 2*10 + 2*5 = 20 + 10 = 30
the second equation becomes 10*5 = 5
both equations confirm that the solution of L = 10 and W = 5 is good.
the ticket can have either:
a length of 5 and a width of 10 or:
a length of 10 and a width of 5.
since the length is usually longer than the width, you are free to choose that the ticket most likely has a length of 10 and a width of 5.
alternatively, you can simply say that the dimensions are 5 by 10 and let the recipient of that information determine which is the length and which is the width.
mathematically, the length can be 10 and the width 5 or the length can be 5 and the width 10.

Answer:
82
Step-by-step explanation:
Vertical rectangle:
A = bh
A = (5)(10)
A = 50
Horizontal rectangle:
h = 10 - (3 + 3)
h = 4
A = bh
A = (8)(4)
A = 32
Combined:
50 + 32
82
Answer:
[tex]A=82 meters^2[/tex]
Step-by-step explanation:
First we will split the shape into two rectangles.
Now that it is in two separate peaces, solve each one individually
Remember [tex]A = l*w[/tex]
[tex]10*5=50[/tex]
[tex]8*4=32[/tex]
Finally add the two areas together
[tex]50+32=82[/tex]

Answer: g(x) = f(x-2)
Step-by-step explanation:
When plugged into desmos, g(x) = 1/4(2^x) - 4
g(x) = f(x-2) is the only equation that lines up with this equation I stated above.
Note: if you try to do this yourself on desmos graphing calculator, make sure to add f(x) first (f(x) is: f(x) = 2^x - 4).

D. 19 houses
Step-by-step explanation:
[tex]\frac{1}{8} +\frac{2}{5} =\frac{21}{40}[/tex]
[tex]1 - \frac{21}{40}=\frac{19}{40}[/tex]
Answer:
D.) 19 houses
Step-by-step explanation:
comany x: 1/8
Company y: 2/5
You need to find the common denominator(in this case is to 40)
1 x 5 = 5 2 x 8 = 16
--------------- ---------------
8 x 5 = 40 5 x 8 = 40
5/40 + 16/40 = 21/40
40 - 21 = 19
SO answer is 19
