Answer:
7.2008*10^5
Step-by-step explanation:
All squares are equal sides.Let X be the side of a square.Area of square,A = x^2
Here a tile is a square of side length 'x'. The following polynomial represents,
(x - 4) represents "the width of the new tile" (because 4 inches cut from the tile)
4x represents "the area removed from the tile" (since one side of removed tile is 'x' and other is 4 inches.)
x2 represents "area of original tile" of side equal to 'x'
x represents "the length of the new tile" (since length of new tile is not reduced. Length =x and breadth is x-4

Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = 2x - 7
5x + 2 = 4
<u>Step 2: Solve for </u><em><u>x</u></em>
- Define equation: 5x + 2 = 4
- Subtract 2 on both sides; 5x = 2
- Divide 5 on both sides: x = 2/5
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = 2x - 7
- Substitute in <em>x</em>: y = 2(2/5) - 7
- Multiply: y = 4/5 - 7
- Subtract: y = -31/5
Answer:
32
Step-by-step explanation:
you have to divide 224 by 7
You should choose 25% of $950 as that gives the higher amount of money.
15% of $1,500 = $225
25% of $950 = $237.5
