X=3, y=4
x=-2, y=9
Set x equal to anything, then isolate y to get the other number.
Answer:
length of each side of the room is 2√30 which is approximately 10.9545 ft
Explanation:
The area of the square can be computed as follows:
Area = l²
where l is the length of the side
We are given that:
area = 120 ft²
Substitute with the area in the above equation and solve for l as follows:
area = l²
120 = l²
l = √120
l = 2√30 ft
This is approximately equal to 10.9545 ft
Hope this helps :)
The answer is 7/8. 1/4 x 3 1/2 = 7/8
Rearrange to standard form:-
x^2 - 10x + y^2 = 11
(x - 5)^2 - 25 + y^2 = 11
(x - 5)^2 + y^2 = 36
Center of circle = (5, 0) and radius = sqrt36 = 6
18+0.07x18= 18+1.26 = 19.26
20-19.26= 0.74
So yes she does
