4x-6
A product means you have to multiply so the product of four and a number is 4 times x so 4x
A difference means you have to substraction a number from another number. So -6
It is c = 48b.
2 x 48 = 96
4 x 48 = 192
9 x 48 = 432
3xy
<span>y(3y)/3xy + y(xy)/3xy + (y+1)(3x)/3xy </span>
<span>NOW since all of the fractions have a denominator of 3xy, drop the denominators and solve using the numerators. </span>
<span>y(3y) + y(xy) + (y+1)(3x) </span>
<span>3y^2 + xy^2 + 3xy +3x </span>
<span>cannot simplify further.</span>
First you have to find the angle B (check attachment)

Then you can find the last angle inside the triangle, which I'll call C

Now you can find angle A
