B): x=8, y=8root2, z=16
c): x=4, y=12, z=8root3
The ones later one you can do by your self.
30 60 90 triangle side ratio: 1:root3:2
90 45 45 triangle side ratio: 1:1:root2
Answer:
t=0, 6, -4
Step-by-step explanation:
first, you can factor out t² of the equation
t²(t²-2t+24)=0, then factor the trinomial
t²(t-6)(t+4)=0, now set each factor equal to zero
t²=0, so t = 0
t-6=0, so t = 6
t+4=0, so t = -4
If you graph it, you can also see the answers.
I believe it would be the third one down
Answer:
(x - 1)(x + 4)
Step-by-step explanation:
What multiplies to (-4) but adds to (3)?
These two values are (4) and (-1). Therefore, these are the values that make up the factored trinomial.
x² + 3x - 4 -----> (x - 1)(x + 4)
You can check your answer by expanding the factors. This is done by multiplying each term within the first parentheses by each term within the second parentheses.
(x - 1)(x + 4) -----> x² - 1x + 4x - 4 -----> x² + 3x - 4
