Answer: a. Diagram B
b. x+2.6=10.4
c. x+2.6=10.4
subtract 2.6 from both sides
x=7.8
d. The solution in the equation represents the amount of water that was in the pitcher prior to Mai poring 2.6 Liters of water in. So there were 7.8 Liters of water in a pitcher, Mai poured 2.6 Liters of water into that same pitchers and the total amount of water in the pitcher was 10.4 Liters.
The area of the triangle could be determined by multiplying the length and the width. Since, we are given the area and the length, to find the width, you divide the area by the length:
w = A ÷ l
w = (x2 - 2x - 15) ÷ (x+3)
What do you have to multiply to (x+3) to yield x2 - 2x - 15? That would be x - 5. Since the sum of -5 and 3 = -2 (middle term) and the their product is -15 (last term).
Hence, the width is (x-5).
A) 2.85g+3.15c
B)2.85(8.4)+3.15(6)=$42.84
