Answer:
Not sure if I correctly did it but Stan is 56$ and Kyle is 44$, unless they meant how much they spent and were left with.
Step-by-step explanation:
50 + 6 = 56
34 + 10 = 44
The answer is y=-3/2x +3 so D
Answer: x = 5/4y + 10
y = 4/5x - 8

Answer:
c. (x^2+1)(x^2+a)-a = x^2(x^2+a+1)
Step-by-step explanation:
You can use FOIL or the distributive property to expand the product of binomials, Then collect terms and factor out the common factor.
(x^2+1)(x^2+a)-a
= x^2(x^2 +a) +1(x^2 +a) -a
= x^4 +ax^2 +x^2 +a -a
= x^4 +ax^2 +x^2
= x^2(x^2 +a +1) . . . . . matches choice C
