X^2 + y^2 = 8
X-y=0 so x = y
replace x = y into X^2 + y^2 = 8
y^2 + y^2 = 8
2y^2 = 8
y^2 = 8/2
y^2 = 4
y = - 2 and y = 2
because x = y
so x = - 2 and x = 2
solutions:
x= - 2 and x = + 2
y= - 2 and y = + 2
Fraid not. This time, you did it left.
The tool to use is "Vertical" angles are equal. (They don't add up to 180 degrees.)
3y + 120 = 5y + 100
(you should fill in the missing steps)
y = 10°
The upper/lower pair of vertical angles are both 150°.
.
2x = 6x - 60
(you should fill in the missing steps)
x = 15°
The left/right pair of vertical angles are both 30°.
It's any two angles NEXT TO each other that add up to 180°.
Notice here that (150° + 30°) = 180° .
Answer:
C
Step-by-step explanation:
factorizing 24:
factors of 24 : 1, 2, 3, 4, 6, 8, 12
looking at your answer choices, we can see that 5 and 7 are not factors of 24, so we can immediately eliminate a and b.
we also see that answer c does indeed contain factors of 24 and they both add to 10. So c is the answer.
Answer:
Volume for cube: L x W x H
L= Length, W= width, H=height
5pi = 15.707
So around 15.707
