Excuse the correction, but "the square of x" should be typed as "x^2."
"x2" is ambiguous. Some people would interpret it as "x times 2," which is incorrect here.
Recall that "area of a rectangle = (length) * (width).
Here the area is x^2+5x+4, and the length of one side is x+2. How woud you determine the width of the rectangle?
Answer: 64
Step-by-step explanation:
the Kids that answered correct in any of questions 1 and 2 got at least one right so subtract the highest number which is 81 students by all the general amount of them, 145 that’s 64.
you divide 72 by 2 to get r by itself and get 36
so r=36
The first sequence is where you need to add the number before it to get the next number. In this case the next number is 24+44 which is 68.
For the next sequence, is all odd numbers. First you, subtract 1, multiply by 3,
subtract 5, multiply by 7. So the
next number is 69 since you have to subtract 9.
Hope this helps! <3
