Answer:GCF=17
To find the greatest common factor, or GCF, of the numbers, we first need to list the prime factors of both 85 and 51
52=3*17
85=5*17
17 is the sole common factor that these two numbers have in common, therefore 17 is the GCF.
To simplify the ratio, simply divide both numbers by 17.
85:51 becomes 5:3
Answer:
The answer is letter A.
(8x³ + 2x² - 7x + 2) ÷ (2x - 1)
8x³ + 2x² - 7x + 2 ÷ 2x - 1
(2x-1)(4x²+3x-2)÷2x-1
cancel 2x-1 so that the answer is 4x²+3x-2.
Answer:

Step-by-step explanation:
Use a cofunction identity on the right hand side or left hand side...
So
.
We have the equation:

Make the above replacement:

Since cotangent has period 180 degrees, we can also write this as:

So solving the following will give us a set of solutions for
:

Add
on both sides:

Subtract 10 on both sides:

Divide both sides by 2:

Symmetric property:

Answer:x = 12,5
using thales's theorem, we have:
