Answer:
x = 50
Step-by-step explanation:
the angle next to x is 65 so the angle on the oposite side will also be 65.
a straight line = 180
so 180 - 65 -65 = 50
x = 50
Factoring out x
x(-3x^2+15x+42) now factor parenthetical expression
x(-3x^2+21x-6x+42)
x(-3x(x-7)-6(x-7))
x(-3x-6)(x-7) we can factor out -3 from first parentheses
-3x(x+2)(x-7)
Answer:

The asnwer is 28. Since 7 is one of the factors,and 7+x=11,you would do 11-7 to find x. After doing 11-7 to find x (4),then you multiply 7 and 4 since they are the factors of the missing number. 7×4 is 28,therefore,you are the number 28.
Answer:
the solution is A
Step-by-step explanation:
(x,y)==> (x-8, y)
(6-8, 4)==> (-2, 4)
