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:
Your answer is 71
Step-by-step explanation:
7+2(n-1)
we have our n as 8
so,7+2(8-1)
9(7)=63
Answer:
the area is 50.24 
.
Step-by-step explanation:
The formula to find area of a circle is A=π
. A is area, and r is for radius. Since we have the diameter here, we just need to divide by 2 to find the radius. 8÷2=4, so there, the radius is 4. Now we need to square 4, and do 4x4, which equals 16. Now to multiply 16 by π, or 3.14. 16 x 3.14 = 50.24. The final answer is 50.24 . Hope this helped! :]
Answer:
C. ±square root of 30
Step-by-step explanation:
Apply the square root function to both sides of the equation:
_____
The absolute value equation has two solutions. They match choice C.
Step 1) Add up the three given angles: 125+109+83 = 317
Step 2) Subtract the result (found in step one) from 360
360 - 317 = 43
The reason for the 360 is because for any four-sided polygon, the angles always add up to 360 degrees.
The answer is 43
