Answer:
A) -13p^33q^-2 or -13p^3/q^2
B) 8x + 5y - 7
C) 15x^2 -23x + 4
Step-by-step explanation:
A) 169/(-13) = -13 p^4/p = p^3 q/q^3 = 1/q^2 which can be written as q^-2 and r/r is 1. So if you put this all together you get -13p^33q^-2 or -13p^3/q^2
B) 3(x +2y) + 5x - (y + 7)
3x + 6y + 5x - y - 7 distributive property
3x + 5x + 6y - y -7 combine like terms
8x + 5y - 7 Answer
C) (3x-4) (5x - 1) Foil multiply the first terms in each parenthesis. the outer terms, the inner terms and the last terms
(3x)(5x) + (3x)(-1) + (-4)(5x) + (-4)(-1)
15x^2 -3x - 20x + 4
15x^2 -23x + 4
12 are 27 1/4 and under and 8 are above 27 1/4
The sum of the two hamsters weight = 1950g
If hamster1 (x) = hamster2 (y) + 300g
Therefore
1950g = x + y
1950g = x + (x +300g)
1950g - 300g = x + x
1650g = 2x
825g = x
Therefore
Hamster1 = x = 825g
Hamster2 = x + 300g = 1125g
The diameter of the circle is 15.99cm.
3? I pretty sure it’s three sorry if I’m wrong
