Answer:
x=-5
Step-by-step explanation:
This equation can be written as
(v-8)(v+5)/ (v-8)(v-3)
= v+5/v-3
I have attached the correct answer. Brainliest will be much appreciated!
Answer:
C
Step-by-step explanation:
If you add all of the numbers above you will get 47 so
32+10+5=47
and of course there are 32 chocolates with orange filling
so the probability is 32/47
Answer:
D
Step-by-step explanation:
Let's substitute a for x²:
x^4 - 3x² - 4
a² - 3a - 4
Now, this looks like something that is much more factorisable:
a² - 3a - 4 = (a - 4)(a + 1)
Plug x² back in for a:
(a - 4)(a + 1)
(x² - 4)(x² + 1)
The first one is a difference of squares, which can be factored into:
x² - 4 = (x + 2)(x - 2)
The second one can also be treated as a difference of squares:
x² + 1 = x² - (-1) = (x + √-1)(x - √-1) = (x + i)(x - i)
The answer is (x + 2)(x - 2)(x + i)(x - i), or D.
