Answer:
-12x+20
Step-by-step explanation:
Subtract similar numbers:
2x - 14x = -12x
Product:
12 - 12x + 8
Group the terms that are similar:
-12x + 12 + 8
Add the numbers:
-12x + 20
Final answer:
-12x + 20
Answer:
4^2 + (-7)^2
Step-by-step explanation:
The square of the distance is given by the distance formula as ...
d^2 = (x2 -x1)^2 + (y2 -y1)^2 = (3 -(-1))^2 + (-5-2)^2
= 4^2 +(-7)^2 . . . . . matches the second choice (sort of)

<em>Comment on notation</em>
Clearly, you understand the use of the caret (^) to signify exponentiation. The number 42 is very different from the value of 4^2 = 16. A caret is required.
