Answer:
(4x - 1)(3x - 1).
Step-by-step explanation:
I think you mean 12x^2 - 7x + 1
= 12x^2 - 4x - 3x + 1
= 4x(3x - 1) -- 1(3x - 1)
= (4x - 1)(3x - 1).
We know that area=0.5*base*height.
Thus, the equation would look like:
127.5=0.5*base*height
That means, 255 = base*height.
We know base is 17
Then, we divide 255 by 17. That gets us the height.
The height equals 15.

Answer:
^geometric sequence^
<h2>YES, it belongs to a geometric sequence because it has a ratio. and how to find ratio is:</h2>
a2 : a1
=9 : 3= 3
or a3 : a2
=27 : 9= 3
or a4 : a3
= 81 : 27= 3
so, the anwer is yes;3 (b)
<h3>FINALLY FOUND, MODERATOR!!</h3>
Answer:
The bear is 35 years of old now.
Step-by-step explanation:
Leon wanted to know the age of the black bear at the zoo.
He is informed that if he adds 10 years to the age of the bear and then doubles it, the bear would be 90 years old.
Let the present age of the bear is x years.
So, according to the above condition we can write
2(x + 10) = 90
⇒ 2x + 20 = 90
⇒ 2x = 70
⇒ x = 35
So, the bear is 35 years of old now. (Answer)
