Answer:
Step-by-step explanation:
First, let's remember the rules:
such that:
Now we have the equation:
First, let's rewrite the roots as we saw above:
We also know that:
and that:
Replacing those two things in our equation, we get:
Where in the final step, I returned to the cubic root form.
P ⇔ Q is equivalent to the pair of conditionals P ⇒ Q and Q ⇒ P.
Your conditional statements are ...
- If two lines intersect to form 4 right angles, then they are perpendicular.
- If two lines are perpendicular, then they intersect to form 4 right angles.
31/200 would be the same as 0.155
Answer:u= -30
Step-by-step explanation:
Answer: aₙ = -12 + (n - 1) 4
Step-by-step explanation:
aₙ = a + (n - 1) d
a = -12
d = 4
aₙ = -12 + (n - 1) 4
