It will take approx.65 of caffeine remaining after 6 hours
SA = LH + LW + WH + 2(1/2LH)
SA = 4*2 + 5*2 + 3*2 + 2*1/2*4*3
SA = 8 + 10 + 6 + 12
SA = 36

General Formulas and Concepts:
<u>Algebra I</u>
Basic Equality Properties
- Multiplication Property of Equality
- Division Property of Equality
- Addition Property of Equality
- Subtraction Property of Equality
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify given.</em>
<em />
<u>Step 2: Solve for </u><u><em>k</em></u>
We can use equality properties to help us rewrite the equation to get <em>k</em> as our subject:
Let's first <em>square both sides</em>:

Next, <em>add p to both sides</em>:

Next, <em>divide 4t by both sides</em>:

We can rewrite the new equation by swapping sides to obtain our final expression:

∴ we have <em>changed</em> the subject of the formula.

Similar figures are the same shape but not the same size. you can find out the scale by using parallel lines.
X=1
because you would add two to the other side and have 2x=2 divide by 2 and you would be left with x=1
