Which expression has a value of 90? 1. 3,600 divided by 50
2. 5,400 divided by 60
3. 6,400 divided by 80
4. 7,200 dived by 90

2.

Step-by-step explanation:

I did the division.

it's number 2

Step-by-step explanation:

5,400/60= 90

you can also do 90 x 60=5,400

can I please have Brainliest since i showed my work

the answe i =−n+5

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
