Answer:
7y(2y+1)
Step-by-step explanation:
a^n + a^n+1
rewrite a^n+1 as a^1 a^n
now you have a^n + a^1a^n
Factor out the common term to get the final answer:
a^n (1+a)
Answer:
4x^3 - 3x^2 - 14x + 6 (this is the formula since we don't know x)
Step-by-step explanation:
[(4x-2) x (x^2 - 3)] - [(x+2) x (x)] = 4x^3 - 3x^2 - 14x + 6
Answer:

)
)
Step-by-step explanation:
Explanation:
Substitute
tan
(
y
x
)
for
θ
tan
(
y
x
)
=
π
3
Obtain
y
x
on the left by using the inverse tangent on both sides:
tan
−
1
(
tan
(
y

)
)
=
tan
−

(
π
3
)
y
x
=
tan
−
1
(
π

)
Multiply both sides by x:
y
=
(
tan
−

)
)
x
