Yes because the adding 4 and 8 would give you the max 12. Then to get the minimum you would subtract 8 and 4 getting 4. The numbers have to fall within that spectrum. They cannot be any more, less, or the exact numbers given.
Remember you can do anything to an equation as long as you do it to both sides
expand by foiling or distributing
4x²-19x-5=-43x-41
add 43x to both sides and add 41 to both sides
4x²+24x+36=0
factor
facotr out of 4
4(x²+6x+9)=0
factor inside
what 2 numbers multiply to get 9 and add to get 6?
3 and 3
4(x+3)(x+3)=0
set to 0
x+3=0
x=-3
x=-3 is answer
A.
-5 is less than 0 so it should be A.
Answer
7:1
Step-by-step explanation:
Simplify both sides by 7
