Answer:
2(2x-5)(2x+5)
Step-by-step explanation:
I think you meant to say 8x^2-50. If so then factoring this down should be easy. Since there is no x value in the middle the equation will have a positive and a negative number. This is also a perfect square therefore, this factors down to: 2(2x-5)(2x+5).

Answer: The director can choose first a lead singer and then a stand-in for the lead singer in 132 ways.
Step-by-step explanation:
Given : The total number of singers auditioning for the school musical.= 12
The director wanted choose first a lead singer and then a stand-in for the lead singer.
We use Permutations here because order of selecting the singers matters.
The number of permutations of selecting r things out of n things = 
Similarly , the number of ways to select 2 singers in an order from 12 singers


Hence, the director can choose first a lead singer and then a stand-in for the lead singer in 132 ways.
Answer:-11/32
Step-by-step explanation:
-7/8 - (-17/32)
= -7/8 + 17/32
The highest common factor is 32
= (-7*4+17)/32
= (-28+17)/32
= -11/32
To find the midpoint, add the two x values together and divide by 2, and then do the same with the Y values.
-3 + 3 = 0
0 / 2 = 0, the X value is 0
-1 + 3 = 2
2/2 = 1, the Y value is 1
The midpoint would be (0,1)
