First it shows 33 points and ok
Eight seven thousand and six hundred and fifty two
24.
This is because the equation you have presented is that of a circle, formulated like so:
x^2 + y^2 = r^2 or radius squared
With that information, you know the find the square of the presented radius which is 12 and the actual radius.
The radius is half of the diameter, which makes the diameter 12 x 2 or 24.
Hope this helps!
Answer:
(- 1, 4 ) and (2, 7 )
Step-by-step explanation:
Given the 2 equations
y = x² + 3 → (1)
y = x + 5 → (2)
Substitute y = x² + 3 into (2)
x² + 3 = x + 5 ← subtract x + 5 from both sides
x² - x - 2 = 0 ← in standard form
(x - 2)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x + 1 = 0 ⇒ x = - 1
Substitute these values into (2) for corresponding values of y
x = 2 : y = 2 + 5 = 7 ⇒ (2, 7 )
x = - 1 : y = - 1 + 5 = 4 ⇒ (- 1, 4 )
Answer
92
Step-by-step explanation:
all you have to do is multiply 34x2 and add 12+12 which is 24 so you should get 92 as your answer
