Answer:
The solution set is (-3, 4).
Step-by-step explanation:
x2 + 4x - 9 = 5x + 3
x^2 + 4x - 5x - 9 - 3 = 0
x^2 -x - 12 = 0
(x - 4)(x + 3) = 0
x = -3, 4.
Answer:
The distance between the points (4,3) and (1,-1) is C. 5 units.
Step-by-step explanation:
Answer:
81 cubic feet of wood
Step-by-step explanation:
Divide it into 5 sections, each 3 feet long because it is 15 feet long.
(1*3*3) + (2*3*3) + (3*3*3) + (2*3*3) + (1*3*3) =
9 + 18 + 27 + 18 + 9 = 81
It goes into 1,440 exactly 90 times.
To figure this problem out on your own, next time, just type into your calculator or work out on your paper 1,440 divided by 16 and then you'll get your answer :)
