n2-6n-16
Step-by-step explanation:
n(n+2)-8(n+2)
n2+2n-8n-16=

Hi friend,
The objective is to divide $20 in 2:3 ratio.
One part be 2x, another part is 3x
Sum of them = 20
2x + 3x = 20
5x = 20
x=4
So therefore one part must be 2x = 2 x 4 = 8
Another part = 3x = 3 x 4 = 12
Hence it is divided in 2:3 ratio.
Hope my answer is helpful to u. :)
Answer:
Step-by-step explanation:
x^2 + 3x - 9 =0
By comparing with the equation ax^2+bx+c = 0,
we get,
a = 1, b=3, c = -9
we know the formula for x is,
x = (-b±√(b^2 - 4ac))/2a
x = (-3±√45)/2
x = (-3±3√5)/2
x = (-3+3√5)/2, (-3-3√5)/2
F-1(x) = (3x + 5) / 3
f-1(3) = (9 + 5) / 3 = 14/3
Answer:
{0,3,5}
Step-by-step explanation:
∩ means "and" so u would want to find out the numbers that repeat in both sets
