2a + 2c = 5a - 5b
recopilar términos ligeros.
toma 2a en el otro lado
2c = 5a -2a-5b
2c = 3a - 5b
divide 2c's 2 en ambos lados
y
c = (3a - 5b) / 2

Answer:
3/-3=-1
Step-by-step explanation:
any number divided by a negative number gives a negative answer
answer:
it is not proportional.
step-by-step explanation:
14-10.50=3.5
17.50-14=3.5
24.50-17.50=7
in order for it to be proportional, they would all have to equal the same number and since in this case, they don't it is non-proportional
hopefully, this helps :)
have a nice day !!
i'm extremely sorry i couldn't help sooner :(
Answer:
x^3 + 4x^2 - 7x - 10
Step-by-step explanation:
To solve this we're going to use Polynomial multiplication, starting by multiplying (x-2)(x+1) = x^2 - 2x + x - 2 = x^2 - x - 2. Next, we will multiply (x^2 - x - 2)(x+ 5) = x^3 + 5x^2 -x^2 - 5x -2x -10 = x^3 + 4x^2 - 7x - 10.
