Answer: fourth choice
Step-by-step explanation:
Answer:
The second one; x²+7x+12
Step-by-step explanation:
So, since the beginning lengths of the square is x and x, the area of the square is x².
But then, you add 3 to one length, so that side is now (x+3), and then you add 4 to the width, so that is now (x+4).
Finally, you would multiply them together to get the equation you would use to find the new area.
For this, you would cross-multiply everything together; the x in the length by the x in the width, the x in the length by the 4 in the width, the 3 in the length by the x in the width, and then the 3 in the length by the 4 in the width. Now, all you have to do is add all of these together to get your answer.
Here's the work:
Answer:
It would be the third answer
Step-by-step explanation:
Answer:
The two numbers are 35 and 36.
Step-by-step explanation:
While you could do this question just by 'guess and check', the best way to do it is to divide 71 by 2, which gives 35.5. So out two numbers should be approximately equal to 35.5. So we just take the two closest: 35, and 36, which are consecutive (consecutive means 'one after the other'), and we see add to 71.
So we see that 35 and 36 is the answer.
