Before we answer the question we must first:
1. Assess what we have so far.
2. Know what we need to find.
3. Solve.
4. Conclude.
Step 1: What we have so far.
*Mt. Everest's height in meters (m) = <span>8847m
Step 2: What we need to find.
*</span>Mt. Everest's height in centimeters (cm) = ?
Step 3: Solve.
*Centi means 100.
*1m = 100cm
Conversion process:
8847m x 100cm/1m <--- we need to multiply Mt. Everest's height to 100cm/1m first because our first agenda is to remove (m) from the value.
8847 x 100cm <--- this will be our working solution.
884,700cm <--- Answer
Step 4: Conclusion.
After successfully doing the steps above, we can now conclude that the height of Mt. Everest in centimeters is: 884,700cm
<span>divide both sides of the equation by 2 to get:
(x + 1/4)^2 = -7/16 ***** this is your solution.
continue further to solve for x if you care to, but the problem did not require you to do this.
take the square root of both sides of the equation to get:
x + 1/4 = plus or minus sqrt(-7/16)
subtract 1/4 from both sides of the equation to get x = -1/4 plus or minus sqrt(-7/16).
since sqrt(-7/16) is the same as sqrt(7/16) * i, your solution becomes:
x = -1/4 plus or minus sqrt(7/16) * i.
your problem was to convert it to the form of (x + p)2 = q.
the solution to that is:
</span><span>(x + 1/4)^2 = -7/16 </span><span>subtract 1 from both sides of the equation to get:
2x^2 + x = -1
factor out a 2 on the left side of the equation to get:
2 * (x^2 + x/2) = -1
complete the squares on x^2 + x/2 to get:
2 * ((x+1/4)^2 - (1/16)) = -1
simplify by distibuting the multiplication to get:
2 * (x+1/4)^2 - 2*(1/16) = -1
simplify further to get:
2 * (x+1/4)^2 - 1/8 = -1
add 1/8 to both sides of the equation to get:
2 * (x + 1/4)^2 = -7/8 .

Answer:
$33.92
Step-by-step explanation:
First, we have to find how much the sale price for the tennis racket is before tax.
100% - 20% = 80% Marcus has to pay 80% of the original price.
80% * 40 = .8 * 40 = 32
Marcus has to pay $32 for the tennis racket before tax.
6% = .06 (tax percentage)
.06 * 32 = 1.92 ————> tax
Add the tax with the sale price.
32 + 1.92 = 33.92
Marcus has to pay $33.92 for the tennis racket.
