Answer:

Step-by-step explanation:
We have been given that the area of a square is given by
, where x is the length of one side.
Mary's original garden was in the shape of a square. She has decided to double the area of her garden. So the new area of Mary's garden will be 2 times the area of original garden.
We can represent this information in an equation as:

Therefore, the expression
will represent the area of Mary's new garden.
To evaluate the area of new garden, if the side length of Mary's original garden was 8 feet, we will substitute x equals 8 in our expression.



Therefore, the area of Mary's new garden will be 128 square feet.
Answer:
3118.7ft
Step-by-step explanation:
Given data
Circumference= 9,799 ft
We want to find the diameter, but we need to get the radius
C= 2πr
9,799=2*22/7*r
9,799=2*3.142*r
9,799=6.284r
r=9,799/6.284
r= 1559.35
Hence the diameter is =1559.35*2
Diameter=3118.7ft
So remember that the distance formula is
.
1.

Distance between (4,-5) and (4,-2) is 3 units.
2.

Distance between (1,1) and (-1,4) is √13 (or 3.61 rounded to the hundreths) units.

Hope it helps! Have a nice day :)
1 quarter = 25 cents (he has 2 therefore its 50 cents)
10 dimes = 100 cents = 1 dollar
Oliver has twice as many dimes than he does quarters because 100 divided by 50 = 2. Hope this helps!
