Hi there! :)
Answer:
x² + 6x + 8 = 0
Factor the equation by finding two numbers that sum up to 6 and multiply into 8:
4 + 2 = 6
4 ×2 = 8
Rewrite in factored form:
(x + 4) (x + 2) = 0
Find the roots using the Zero-Product Property:
x + 4 = 0
x = - 4
x + 2 = 0
x = -2.
Therefore, the roots of this equation are at x = -4 and -2.
Answer:
The volume of sphere is 36π cm³
B is correct.
Step-by-step explanation:
A sphere has a radius of 3 cm.
We need to find the volume of sphere.
Formula:
where,
r is radius of sphere.
Put r=3 into formula
Hence, The volume of sphere is 36π cm³
3 angles in a triangle need to = 180 degrees
so you have 2x+3x+4x = 180
9x = 180
x = 180/9
x = 20
Answer is A
