Step-by-step explanation:
Answer:
14a^2(2a^6+1)
Step-by-step explanation:
V = 1/3 × (pie) × radius^2 × height of cone
30 + 2x = 90
2x = 60
x = 30
Answer:
x = 30
Easy...
to even begin to factor..you must factor out a 3, to simplify your answer.
3(12

-7x-10)
Now, you can factor.

So..to find the answer...
12*-10=-120x
and
you would use -7x
What multiplies to -120..but adds to -7?
-15*8=-120
and
-15+8=-7
To find the answer, plug in what you know..
3(3x+2)(4x-5)
Thus, your answer.
