Answer:
25 so C
Step-by-step explanation:
Trinomial 2x² + 4x + 4.
It's of the form ax²+bx+c and it's discriminant is Δ=b² - 4.a.c
(in our case Δ = 4² - (4)(2)(4) → Δ = - 32
We know that: x' = -1 + i and x" = -1 - i
If Δ > 0 we have 2 rational solutions x' and x"
If Δ = 0 we have1 rational solution x' = x"
If Δ < 0 we have 2 complex solutions x' and x", that are conjugate
In our example we have Δ = - 16 then <0 so we have 2 complex solutions
That are x'= [-b+√Δ]/2.a and x" = [-b-√Δ]/2.a
x' =
A prime number is a number that can have factors that is only 1 and itself. A composite number is a number that can have many differnt factors.
Replace values of n in expression with 1/4.
9(1/4 + 2) - 5(1/4)
Distributive property
9/4 + 2 - 5/4
Rearrange.
2 + 9/4 - 5/4
Subtract.
2 + 4/4
Simplify.
2 + 1
3.
<h3>The expression is equal to 3 when n = 1/4. </h3>
Answer:
6:5
Step-by-step explanation:
I am thinking it would be 6:5 because you have 6 dogs, and 5 cats. So, you could think of it as for every 6 dogs you have 5 cats at the kennel.
