The perimeter and area of the top of the child's desk are 120 inch and 864 inch² respectively.
<u><em>Explanation</em></u>
Dimensions of the top of the adult's desk : Length = 54 inches and Width = 36 inches.
As the dimensions of the child's desk are 
of the dimensions of the adult desk, so....
Length of child's desk 
inches and
Width of child's desk 
inches.
So, the perimeter of the top of the child's desk 
inches.
and the area of the top of the child's desk 
inch²
Answer:
21:8
Step-by-step explanation:
<u>Given information:</u>
Lori (x) is 8 years old.
In 5 years (x + 5), Philip will be twice Lori's age (y + 5 = 2(x + 5))
<u>The missing value, y, is needed to find the ratio for Lori's and Philip's ages in the present. To find y, solve this equation:</u>
y + 5 = 2(x + 5) First, distribute the 2 into x + 5.
y + 5 = 2x + 10 Next, isolate the variable y by subtracting 5 from both sides.
y = 2x + 5 After that, add in the value of x, 8.
y = 2(8) + 5 Finally, simplify the right side to find Philip's age.
y = 16 + 5
y = 21
<u>Now for the easiest part: The ratio of Philip's age now to Lori's age now.</u>
because 21 is not divisible by any of 8's factors, the current ratio of 21:8 cannot be simplified further.
So, the ratio is 21:8
Answer:
L(w) = 8 mm + (2 mm/wk)(wk)
Step-by-step explanation:
L(w) = length of beard as a function of time in weeks
L(w) = 8 mm + (2 mm/wk)(wk)
4mm
The sides of the new garden can be represented by x+9. x is the original size and 9 is the added 9mm. Multiply the sides to get (x+9)(x+9) or
this will equal the area. Create an equation to solve for the unknown original length.
Take the square root of both sides
13=x+9
Subtract both sides by 9
4=x The original side was 4mm long
