sorry i dunno i really dont i just need to finish my test lol
Answer:
<h2>350 children</h2>
Step-by-step explanation:
x = Number of adults
x + x + 68 = 632
2x = 632 - 68
2x = 564
x = 282
282 + 68 = 350
350 children.
We can always check.
282 + 350 =
It equals 632, so we know our answer is correct.
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' =
