Can you help me with number 5?

We can divide that up into two rectangles, say the bottom one 8 feet wide and 2 feet high.  That leaves 5.5 by 6-2=4 feet for the other.

Cost = price × area = 2.25(8×2 + 5.5×4) = $85.50

$85.50

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
