The correct option is (B): (3x+2)(3x+1)

Explanation:
Add all the boxes:
9x^2 (boxes)
9x (boxes)
The constants = 2

So it becomes:
9x^2 + 9x + 2
9x^2 + 6x + 3x + 2
3x(3x+2) + 1(3x+2)

(3x+2)(3x+1)

When 31 times a number is increased by 40, the answer is the same as when 200 is decreased by the number. Find the number.
natulia [17]

Answer:

The Answer is: 5.

Step-by-step explanation:

Let n = number.

The number times 31 plus 40 is equal to 200 minus the number:

31n + 40 = 200 - n

32n = 200 - 40

32n = 160

n = 5

Proof:

31(5) + 40 = 200 - 5

155 + 40 = 195

195 = 195

Hope this helps! Have an Awesome Day!! :-)
