Answer:
Step-by-step explanation:
(x^2+8x+8)+(-10x^2+5x) = (x^2-10x^2) + (8x+5x) + 8
= -x^2 +13x + 8
3,301927249 = ³√36
As discussed in one of my videos on my channel [USERNAME: MATHEMATICS WIZARD] on the Six Rational Exponential Rules, this one states that with a numerator of 1 in the exponent, you take the multiplicative inverse [reciprocal] of the fraction, and set the whole number equal to the root, bringing your a inside the radical, which is 36.
ⁿ√aᵐ = aᵐ\ⁿ → works for both: numerator ≥ 1

Answer:5
Step-by-step explanation:there are 6 boxes between the top of the 3rd box and the bottom of the 10th box.
Since each box is 10 inches tall, the length of the 6 boxes sum up to 60 inches.
and since 12 inches =1 feet,
Then 60 inches = 5 feet
How to solve
Let "y" = the unknown number of feet's
12 inches = 1 feet
60 inches = y
Cross multiply
> 12×y =60×1
> 12y =60
Divide both sides by 12 since you want the value of "y".
> 12y÷12=60÷12
So 12 cancels out leaving the final answer to be:
> y=5
Answer:
B. 300
Step-by-step explanation:
Final figure volume = big cuboid volume - small cuboid volume
Volume of a cuboid = height x width x length
Final figure = (6 x 6 x 15) - (4 x 4 x 15)
Final figure = 540 - 240
Final figure = 300mm^2
