Complete the area model to identify the factored form of the quadratic expression it represents.
(c + 3)(c + 8)
B)
(C - 3)(c + 8)
(c + 3)(c – 8)
(c - 3)( -8)

Plz hurry evaluate the expression a+b where a=8 and b=19

The weight of a radioactive isotope was 96 grams at the start of an experiment. after one hour, the weight of the isotope was half of its initial weight. after two hours, the weight of the isotope was half of its weight the previous hour. if this pattern continues, which of the following graphs represents the weight of the radioactive isotope over time? a. graph w b. graph x c. graph y d. graph z

Use the irregular polygon below. show all work. a. find the perimeter. b. find the area. the angles of the irregular polygon is 2, 8, 8, and 4.
