In order to determine volume you should multiple w*d*h. So in this case 5*6*3 or 90 cubic meters.
Answer: this is just algebra, so you just got to add 3 plus 12 and then add the X at the end cause you don't know it's value.
Step-by-step explanation:
In this case you are multiplying 3 times X so it would stay as 3 and just add 12 = 15 X
Hope I helped.
Answer: D
Step-by-step explanation:
From the equation given , ( -3)⁰(2x⁻¹y⁻¹)²
Recall :From the laws of indicies,
x⁰ = 1 ,and (xᵃ)ᵇ = xᵃ ˣ ᵇ = xᵃᵇ. and x⁻¹ = 1/ₓ
Therefore,
(-3)⁰ = 1,
( 2x⁻¹y⁻1 )² = 2²x⁻¹ ˣ ²y⁻¹ x ²
= 2²x⁻²y⁻²
=4x⁻²y⁻²
Now going by the law above, the expression will be
=4/ₓ²y²
So the answer is D
Yes! The lengths of each side must be less than the sum of the other two lengths. It looks like this:
4+4>7
7+4>4
4+7>4
