Answer:
The other length would be 6.
Step-by-step explanation:
Rectangle area is l times height. So x is either the length for height. So we have 5 times x = 30. To find the other length we have to take 30/5 which equals 6
Simplify the expression.
Answer:
the simplified expression is 108x
Step-by-step explanation:
4x(22+5)
you can remove the parenthesis by multiplying 4x by everything inside of them.
4x * 22 + 4x * 5
88x + 20x
108x
Answer:
The required simplest form is:
Step-by-step explanation:
We have been given Kyle has 125 marbles.
And 50 out of total 125 are red and rest of them are other colours
that means other colour marble are 125-50=75
we need to find ratio of the number of red marbles to the total of marbles
The ratio is:
The required simplest form is:
Answer:
Step-by-step explanation:
2/5
Answer:
Correct answer: V = 486 π ft³
Step-by-step explanation:
Given:
Diameter of the sphere d = 18 ft
d = 2 · r where r is radius
r = d / 2 = 18 / 2 = 9 ft
r = 9 ft
V = (2/3) · r³· π
V = (2/3) · 9³ · π = (2/3) · 729 · π = 486 π ft³
V = 486 π ft³

Answer:
C.
Step-by-step explanation:
We have been given 4 expressions and we are asked to choose the expression that is a perfect square trinomial.
We know that a perfect square trinomial is in form: .
Upon looking at our given choices we can see that option C is the correct choice as we can write as:
Therefore, option C is the correct choice.
A perfect square trinomial is found in the expression where both the leading coefficients and the constant are both perfect squares. That only is the case with the third choice above. 16 is a perfect square of 4 times 4, and 9 is a perfect square of 3 times 3. We need to set it up into its perfect square factors and FOIL to make sure, so let's do that. Not only is 16 a perfect square in that first term, but so is x-squared. Not only is 9 a perfect square in the third term, but so is y-squared. So our factors will look like this:
(4x + 3y)(4x + 3y). FOIL that out to see that it does in fact give you back the polynomial that is the third choice down.
