Expanding the left side gives

which gives two solutions,

and

. But if

, then

, but this number isn't real, so

is an extraneous solution. Meanwhile if

, you get

, so this solution is correct.
"Potential solutions" might refer to both possibilities, but there is only one actual (real) solution.
Step-by-step explanation:
Let's make the number we're finding to be
. So, it says that it will be divided by 4 and then added by 12 if we want this in algebraic expression it will be
. It's also telling us that that expression is the same thing as our number divided by 3 and subtracted by 5. If we want an expression out of it it well be
. Since they are the same, we have the equation below.

All we have to do now is to find
.

<h3>Answer:</h3>
Our number must be
. I think
Answer:
<u>Surface area = the sum of the area of all six sides:</u>
(11 · 10) + (11 · 10) + (11 · 8) + (11 · 8) + (8 · 10) + (8 · 10)
= 110 + 110 + 88 + 88 + 80 + 80
= 220 + 176 + 160
= 556 ft²
Answer:
y = x + 2
Step-by-step explanation:
Step 1: Find the slope

Step 2: Substitute the slope and a point in to find y intercept
(6)=(1)(4)+b
6 = 4 + b
b = 2
Step 3: Substitute all the information in
y = x + 2
Therefore the equation for a line that passes through (4,6) and (-1,1) is y = x + 2
