Welll to simplify 4/40 divide 4 by 4 to get 1 and 40 divided by 4 to get 10 to get 1/10
Hello,
Why "Multiply the polynomial by distribution" ?
It's s t u p i d, you compliquate the equation.
In order to find the roots of P(a)=(a-3)(a²+2a-6)=0
a²+2a-6
=(a²+2a+1)-7
=(a+1)²-7
=(a-√7)(a+√7)
P(a)=(a-3)(a-√7)(a+√7)
Roots are 3,√7 and -√7
(If i have well understood the question , sorry if not)
30 + 1x = 18 + 5x
subtract 18 from both sides
30 - 18 + 1x = 18 - 18 + 5x
12 + 1x = 5x
subtract 1x from both sides
12 + 1x - 1x = 5x - 1x
12 = 4x
To clear the multiplication by 4, divide both sides by 4
12/4 = 4x/4
3 = x
It will take 3 months until they have the same amount of CD's
They will each have 33 CD's
Answer:
ABC = 87°
Step-by-step explanation:
So ABC is x + 32 because the angles are vertical. ABC is also supplementary to ABD so you can make an equation.
3x + 15 = 180
3x = 165
x = 55
ABC = 55 + 32 = 87
