Step-by-step explanation:
It seems here that they are asking us to solve for x
to do this we first need to factor
Since we can't factor this using the normal method we can instead do this
x^2 -4x-17=0
add 4 to both sides as it is a perfect square
x^2 - 4x + 4 = 17 +4
(x-2)^2 = sqrt 21
x-2 = ± 4.58
x -2 = 4.58 x-2 = -4.58
x= 6.58 x=-2.58
Or just say x=2+√21 or x=2−√21
Answer:
2
Step-by-step explanation:
4x+3=x+9
4x-x=9-3
3x=6
x=6/3
x=2
You would subtract.
The question is asking who has more, so to find out, you need to take away the smaller amount from the bigger amount. (1.25-1.05)
So Sandra bought more candy. Hope this helps!
The way to solve this is by doing 16/2 which is 8=8 and 4 multiplied by 8 will be 8=8
