Answer:
Step-by-step explanation:
Put the square roots together
4*5 * sqrt(14z^2 * 21z^3)
4*5 * sqrt(2*7 * z^2 * 3*7 z^2 * z)
The rule is to remove the perfect square from under the square root sign, you take 1 member of the perfect square out of the root sign, and throw the other one away. If there are an odd number of factors under the root sign, leave one of them alone.
4*5 * 7 z * z sqrt(2 * 3 * z)
140 z^2 * sqrt(6z)
Answer:
4/3 inches, or 1.33333 inches
Step-by-step explanation:
In terms of the volume of a cube, its side length is the cube root of it. Therefore, for a cube with a volume of 512/216 cubic inches, its side length is equal to ∛(512/216) = ∛(512)/∛(216) = 8/6 = 4/3 inches*
* we know that 8/6 = 4/3 because we can multiply both the numerator and denominator by 1/2 to get this result. If we multiply/divide the numerator or denominator by the same values, the fraction is still the same
Answer:
y=-3/4x+2
Step-by-step explanation:
The b in 'y=mx+b' is 2 because thats where the line crosses on the y-axis. When finding the slope which is m in this situation keep in mind, rise over run. Now obviously this line is descending so we have to count down to where the next solid point is. In this case we count down to 3. Then we run or go over to the point which is 4 spaces over. Since our line is descending its a negative.
Hence, y=-3/4+2

Answer:
y=2x2+12x+23
Step-by-step explanation:
2×2+12x+23
2(2+6x)+23
2×2(1+3x)+23
2(1+3x)2+23
I hope it will help you.
1 liter and 40 centiliters. 1 liter holds 100 centiliters, so 200 - 60 = 140 centiliters or 1 liter and 40 centiliters.
