Answer:
x = -6
Step-by-step explanation:
3/ x = 4/(x-2)
Using cross products
3 (x-2) = 4x
Distribute
3x - 6 = 4x
Subtract 3x from each side
3x-3x-6 = 4x-3x
-6 =x
Answer:
it lies in Quadrant 1
Step-by-step explanation:
The points are positive so in the first one
If the inscribed square has sides of 8in, the diameter of the circle is equal to the diagonal of the square.
d^2=x^2+x^2
d^2=2x^2
d=√(2x^2)
Since d=2r, r=d/2 so
r=(1/2)√(2x^2)
r=√((2x^2)/4)
r=√(x^2/2), since x=8
r=√(64/2)
r=√32
r=√(16*2)
r=4√2 in (exact)
r≈5.66 in (to nearest hundredth of an inch)
Answer:
C) 324 cm^3
Step-by-step explanation:
So you know the volume and 2 side lengths. 360 divided by 12 divided by 5 to find the third side. The third side is 360 / 60 (answer of 12x5), which is 6. Surface area of prism is 324 (c)
I'm not entirely sure but I believe it would be 8=22-x because x=16 so 8 does equal 22-16
