You would add because that is just how i thought of it
Okay so a dilation means that you would multiply the area by your scale factor. 103 times 3 is 309. Your answer is 309
The value of a is 
Step-by-step explanation:
<u>1. Determine the other solution of x</u>
If one value is 5 +
then the other value is 5 - 
<u>2. Use reverse technique to find the equation</u>
(5 +
) (5 -
) = 0
25 -
+
-
= 0
-
+ 25 = 0
<u>3. The equation is</u> -
+ 25 = 0
<u>4. Find the value of a</u>
a is the number with the variable
therefore it is -

The final price is the cost plus the tax.
Since we know the tax and a percent, we can write this as
T = C(1+r)
T = what Graham paid = $87.45
C = cost before tax
r = tax rate expressed as a decimal = .40
Plugging in what we know
87.45 = C (1+.4)
87.45 = C(1.4)
Divide both sides by 1.4
C = $62.46
