Answer:
the answer is 640
Step-by-step explanation:
-280-360 = 640
d(t)=-360
= 360*d*t
(2x+24)
(11b-33)
(8s-8)
(36+6y)
(25z-100)
(35w-70)
Answer:
Radius of the given circle is r = 2.
Step-by-step explanation:
Given equation of the circle is
.
Now we need to find the radius of the given circle
.
To find that let's compare with the formula of the circle with is
, where r is the radius.
We get 
take square root of both sides.

Hence radius of the given circle is r = 2.
Ratio is the comparison of sizes of two quantities of the same unit. Proportions are the equality of two ratios. A/b =c/d
