Please help I'm confused. If you explain well I'll give brainliest. Part 1: You trimmed a large square picture so that you could fit it into a frame. The area of the cut picture is 20 square inches. If we want to find the area of the original picture, what equation would I use? *Remember Area of rectangle = length x width
A.20=(x−5)(x−6) B.20=(x + 5)(x + 6) C.20=x squared D.20=5x+6x
Part 2: A. x=1, so Area=42 square inches B. x=10, so Area= 100 square inches C. x=10, so Area=300 square inches D.20=5x+6x x=1, so Area = 1 square inch

If t8 = 4 and t12 = −2, find the first three terms of the arithmetic sequence.

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
