Let the red beans be 5x and green beans be 9x
Then,
total beans = 5x + 9x =14x
∴ The fraction of beans that are red = No. of red beans / Total beans
= 5x/14x
= 5/14
3 x 7 because three, seven times is 21
Answer:
f(x) = x^2 ( x -4i) (x+4i)
Step-by-step explanation:
f(x) = x^4 + 16x^2
Factor out x^2
f(x) = x^2 ( x^2 +16)
f(x) = x^2 ( x^2 - -16)
The square root of -16 is 4i and -4i
Using the difference of square (a^2 - b^2) = (a-b)(a+b)
f(x) = x^2 ( x -4i) (x+4i)
So y=-2+3 means y=3-2
y=1
so then subsitute 1 for y and solve
1=1/3x-1
add 1 to both sides
2=1/3x
multiply boht sides by 3
6=x
so x=6
y=1
