Do 35 times 19 and that is the whole square inches or so 35 squared times 19 squared

Step-by-step explanation:
We know that
cos 2x = 2cos²x - 1
So we have

Substituting 

For this fraction, we have (3x+2) in both the numerator and the denominator. So, they will be cancelled together.
Then we can notice that we can divide the coefficients in the numerator and the denominator by 9 as 36/9 = 4 and 9/9 = 1
So, the expression now becomes:
(x+7) / 4(x-5) which is the simplest form.
Answer:
Step-by-step explanation:
1/5x = 12
x = 12 × 5
x = 60
( By using transposing method )
Plz mark it as brainliest
You can recheck it by calculating
60/5= 12
