1.
2.
3.
Step-by-step explanation:
1. Both and 64 are perfect squares, meaning is twice the product of x and 8. Since all signs are positive, the equation would be: . Let and . Answer: or .
2. Since -3 is a factor of all 3 terms, factor out the -3 which makes, . K is also a common factor, so you would factor that out too, . Then simply, find the two factors whose product is -2 and whose sum is -5. Answer: .
3. By factoring , you would break the expressions in the group=. Then, factor out "x" from . Factor out "5" from = . Finally, factor out the common term "3x-1" =
Number 11 would be y= 9x- 6
Answer:
45 I think is the answer it's my guess
