It could be anything they are both variables.
Answer:
1. (x+5)(x-1)
6. (3x+4)(x-6)
9. (x+5)(x-5)
Step-by-step explanation:
To factor an equation, break the polynomial into two binomials which multiply to make it. There are three main ways to factor:
Regular: Find two numbers that multiply to C and add to B from
.

Grouping: Find two numbers that multiply to A*C and add to B. Then split B into the two factors and factor by GCF.

Difference of Squares: Factor by taking the square root of each term. 

First you find common denominators then change the numerator to match it. In this case Kira's fish weighed more. (7/8)
16/24
21/24
Solution is x= -9.297 or -9.30 rounded and y= 5.6
Answer:
1) At least two equal sides
2) One pair of equal angles
