Answer:
x -4, y -1 2. x3.5, y-1
Step-by-step explanation:
2(3x + 5) (x - 1)
This is done through factoring 2 out of the equation first...
2(3x^2 + 2x -5)
And then cross multiplying it
Normally, you would do whatever is inside of the parenthesees first then do the rest but we cant get any further so we remove the parenthasees by distrubtion
7a+6b-4(3a-3b)
-4(3a-3b)
a(b+c)=(ab)+(ac)
-4(3a-3b)=-12a-(-12b)
7a+6b-12a+12b
7a-12a+6b+12b
-5a+18b
that's the asnwer
Basically what you have to do is multiply the two numbers that are mentioned and that will be your answer.
This is because the item will have the same amount or length and you just need to find what it will be with multiple ones.
Next time you could highlight keywords that help you understand if you are supposed to multiply, divide, subtract, or add.
