Answer: x(.25)+(4+x(.25))=y
Step-by-step explanation:
1. set up the equation-
Ali has an unknown amount of quarters so make that x.
We know quarters are 25 cents so .25 if he has one quarter you put that one quarter into x, 2 into x and so on
Tom has 4 more, since he has 4 more it is 4+x and one again times .25
2. that is it
Answer:
D = 0; one real root
Step-by-step explanation:
Discriminant Formula:

First, arrange the expression or equation in ax^2+bx+c = 0.

Add both sides by 9.

Compare the coefficients so we can substitute in the formula.

Substitute a = 1, b = 6 and c = 9 in the formula.

Since D = 0, the type of solution is one real root.
Answer:
The width of the photo is
.
Step-by-step explanation:
From the given figure it is notices that the total width of the frame is

The photo is covered by a frame border and the width of the border is

To find the width of the photo we have to subtract the width of upper frame border and lower frame border from the total width of frame.
Width of the photo is




Therefore the width of the photo is
.
7+5=12 so it can be one of these 8+4=12, 9+3=12, 10+2=12, and 11+1=12.
