Answer:
The answer is 686 but I coukd be wrong.
To find the correct polynomial, we can use the answers to help us out. The middle variable must be the sum of +2 and another number; the last number in the equation must be the product of +2 and the other number.
Knowing this information, we can use the process of elimination to find the exact polynomial that contains the factor (3x + 2).
A) This can't be it because to get -x as the middle variable, you would need to add -3 and +2. However, -3 x +2 doesn't equal -4.
B) This equation isn't the right one because to get +8 you need to add +6 + 2. However, the product of these two isn't -8.
C) Can't be correct because +2 and -7 = -5, but 2 x -7 = -14...not -9.
D) Is the correct answer because you can add 2 and -1 to get +1. (There is an understood +1 in front of the x in the equation.) The product of 2 and -1 equals -2, which happens to be the last number inside this equation. Therefore, this (D) is the correct answer choice.

Answer:
$135
Step-by-step explanation:
Given data
Amount paid for new surfboard= $81
Percentage of the savings paid= 60%
Let the amount of the savings be x
Hence
60% of x= 81
60/100*x= 81
0.6x=81
x= 81/0.6
x=$135
Hence his savings was $135
Step-by-step explanation:
perimeter=(L+W)2
L=x^2+2x-3
W=2x^2+3x+5
(x^2+2x-3+2x^2+3x+5)2
(x^2+2x^2+2x+3x-3+5)2
(3x^2+5x+2)2
p=(6x^2+10x+4)units
Answer:
1a: f(-2) means substituting -2 for x
1b: 65
I don't know the second one
