FOIL
x^2+11x-9x-99
x^2+2x-99
Answer:
the furthest one to the left
Step-by-step explanation:
this is because none of the xs repeat themseleves
Answer:
x = -9
Step-by-step explanation:
12 + 2x + 24 = 27 + x
(12 + 24) + 2x = 27 + x
36 + 2x = 27 + x
subtract 27 from both sides
36-27 + 2x = 27-27 + x
9 + 2x = x
subtract x from both sides
9 + x = 0
subtract 9 from both sides
x = -9
(the steps could've been faster but that shows the most work)
check:
12 + 2(-9) + 24 = 27 + (-9)
36 - 18 = 18
18 = 18
True!
so -9 is correct
The correct answer is y = 3x + 2y.
first make them into improper fractions 124/15 and 54/15 then subtract so it would be 70/15 then turn it into a mixed number 4 10/15
