Answer:
x= 4, -1
Step-by-step explanation:
-2x - 2 + x^2 + x + 180 - 2x - 2 = 180
add like terms and put in descending order
x^2 - 3x + 176 = 180
subtract 180 from both sides
x^2 - 3x - 4 = 0
factor out the equation
(x-4)(x+1)=0
solve for x
x-4=0 x+1=0
x=4 x=-1
Answer:
the one with pink and white at the top, and the same one with purple and blue on the bottom
Step-by-step explanation:
i think <span>The bag contains 18 red marbles and 12 blue marbles.</span>
Using addition
x-y+1/2x+y=1+5
x+1/2x+0y=6
3/2x=6
3x=12
x=4
Using the value of x
x-y=1
4-y=1
y=3
With x as 4 and y as 3, their product is 12
And can be written as (4,3)
