The sum of all three numbers is 47.
Answer:
C. In y^2-y=6, 6 should have been subtracted on both sides first.
Step-by-step explanation:
It is a quadratic equation so you subtract the 6 and create
y^2-y-6=0
Then you factor it to:
(y-3)(y+2)=0
The solutions then are:
y-3=0, y=3 and y+2=0, y=-2
{-2,3}
Answer: B,C,D,E
Step-by-step explanation: do the abc's its easy you should try.
Answer:
Step-by-step explanation:
To isolate the x, we need to multiply both sides by the denominator. For example, in the equation , we can multiply both sides by 2 to get , so x = 3.
Height (h) = 24 mm
Diameter = 6 mm
Radius (r) =
= 3 mm
Area =
= 216 * 3.14 = 678.24 mm²
