Every number has three cube roots.
The only real cube root of -64 is <em>-4</em> .
The other two cube roots of -64 are a pair of complex conjugates.
I'm too lazy to calculate them right now, and you didn't ask for them
anyway.
False.
Any two right triangles, similar or not, must have one pair of congruent angles, the right angles.
If one pair of acute angles angles is congruent, then by AA Similarity, the triangles are similar.
Therefore, for two right triangles to not be similar, neither of the acute angles of one triangle may be congruent to an acute angle of the other triangle
Answer: 4 (20 minus 16 y): Each side measures 20 minus 16 y units.
Step-by-step explanation:
Hi, to answer this question we have to know the formula of the perimeter of a square:
Perimeter = side length x 4
Since:
p = 80-64y = s x 4
Solving for s (side length)
80-64y /4 = s
s = 20- 16 y
So, the correct option is:
4 (20 minus 16 y): Each side measures 20 minus 16 y units.

Answer: The cost for 20 people equals $180.
Step-by-step explanation:
Given: It costs $100 to rent the bowling alley, plus $4 per person.
The cost for any number (n) of people can be found using the expression
We can find the cost for 20 people by substituting n=20 in the above expression, we get
Hence, The cost for 20 people equals $180.
18 is your final answer when been simplify
