Answer:
Step-by-step explanation:
can you explain
The answer is x2 + 2xy + y2.
Standard form for circle with radius r and center (h,k) is
(x-h)^2+(y-k)^2=r^2
r=36
center at -2,-7
(x-(-2))^2+(y-(-7))^2=36^2
(x+2)^2+(y+7)^2=1296
firts option
Well you will need two number that are divisible by 30 and add up to -7 so they will have to be a negative.
I would try -2 and -5 which are both divisible by 30 and ad up to -7 so...
-2/30 + -5/30 = -7/30
Answer:



Step-by-step explanation:
3) Area of a circle is

Where r = 6
Thus,




4) False
Area of a circle is measured by the formula below:

5) The formula for calculating the area of a rectangle is given thus:

Where, l = 10ft; w = 7ft
