Answer:
16b^4-9
Step-by-step explanation:
Factoring gives us 16b^4+12b^2-12^2-9. Simplifying gives us the answer which is 16b^4-9
Ok, l = lewa's backpack and a= alai's. :)
1/2a -5 = l.
so to solve,
1/2 (36) - 5 = l.
18 - 5 = l.
13 = l.
so Lewa's backpack weighs 13 pounds. Hope it helps!
Answer:
45 stickers
Step-by-step explanation:
630/42 = 15 (represents the number of stickers in each pack)
Since there ar 3 packs, we multiply 15 by 3.
3 x 15 = 45
45 stickers.
tadah!
X^2 - 4x + 2
d = b^2 - 4ac, where a = 1, b = -4 and c = 2
d = (-4)^2 - 4 x 1 x 2
d = 16 - 8
d = 8
Y=12.5x
because 12.5 is the constant and this is a directly proportional equation
