Pattern: 4, 10, 18, 28, 40, 54, 70, 88, 108, 130 Since the second difference is constant in the pattern above, the algebraic
expression will have degree 2. In an expression of degree 2, the largest
exponent is 2. Therefore, we know that the expression for this pattern must
include n^2. What is the algebraic expression for the nth term in this pattern?

What is the perimeter, p, of a rectangle that has a length of x + 8 and a width of y − 1? p = 2x + 2y + 18 p = 2x + 2y + 14 p = x + y − 9 p = x + y + 7

14 pointslet x be the seats in the small van and y the seats in the large van. how many seats does the large van have? a company uses two vans to transport worker from a free parking lot to the workplace between 7: 00 and 9: 00a.m. one van has 9 more seats than the other. the smaller van makes two trips every morning while the larger one makes only one trip. the two vans can transport 69 people, maximum.how many seats does the larger van have?

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much
