Answer:
2.48 kg
Step-by-step explanation:
1 - ⅗ = ⅖
⅖ × 6.2 = 2.48
Answer:
x=-2
Step-by-step explanation:
14+6x=2
Then u move 14 to the other side since it doesn't have a a variable and 2 doesnt also there both just numbers so 14 moved to the otehr side will be -14 so 6x=2-14
6x=-12
x=-12/6=-2
Answer:
Step-by-step explanation:
f(x) = x^2 - 2x + 6
to find f(-1), we sub in -1 for every x
f(-1) = (-1^2) - 2(-1) + 6
f(-1) = 1 + 2 + 6
f(-1) = 9 <=======
Answer:
0
Step-by-step explanation:
Rewrite the equation as x^2-3x+9=0
find the determinant.
D = b^2-4ac = (-3)^2-4*1*9 <0

Answer:
5 centimeters
Step-by-step explanation:
We know the equation to find volume is V = B x h, where B is the base of the prism. (It is also known as the simple V = l x w x h.)
No matter what equation you use, you will end up with V = l x w x h, since the base of a rectangular prism is length x width. So, we're going to plug in our known information to get 420 = 6 x 14 x h.
Then, we're going to multiply 6 x 14 to get 84. Now we have 420 = 84 x h. To isolate the h (in order to find what it is), we must divide both sides by 84.
420/84 = 5, so whats left of the equation is 5 = h, meaning your height is 5 centimeters.
