Answer:
176.71cm^2
Step-by-step explanation:
Area of a circle is pi*radius^2
your radius is given to you, which is 7.5
pi*7.5^2 in a calculator gives you 176.71

No Solution
Done
8x + By + 92 = 0
(-4; 12) ⇒ x = -4; y = 12
subtitute
8 · (-4) + 12B + 92 = 0
-32 + 12B + 92 = 0
12B + 60 = 0 |subtract 60 from both sides
12B = -60 |divide both sides by 12
B = -5
Answer:
Step-by-step explanation:
I dont quite understand the problem but this is one way to solve it using completing the square:-
2x^2 + 8x - 12 = 0
2(x^2 + 4x) - 12 = 0
2((x + 2)^2 - 4) = 12
2(x + 2)^2 - 8 + 8 = 12 + 8
2(x + 2)^2 = 20
