What is the radius of a circle with the equation x2 + y2 – 14x + 10y = 250? a) 9 units b) 12 units c) 15 units d) 18 units

Option (d) is correct.

Radius of given equation is 18 units.

Step-by-step explanation:

Given : The equation of circle as

We have to find the radius of given circle.

Consider the given equation of circle

The standard equation of circle with center (h,k) and radius r is given as

Rewriting in standard form, we have,

Grouping x and y variables, we have,

Convert x terms to perfect square term by adding 49 both side, we have,

Simplify, we have,

Convert y  terms to perfect square term by adding 25 both side, we have,

Simplify, we have,

Thus, standard form is

Thus, radius of given equation is 18 units.

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

0

step-by-step explanation:

you can not divide by 0 so 4 ÷ 0 would be 0

0 × 9999 =0
