$(x-3)(2x+5)=2x^2+5x-6x-15=\boxed{2x^2-x-15}\\\\(3x+7)(2x-1)=6x^2-3x+14x-7=\boxed{6x^2+11x-7}$

Q # ..19 anybody help me?

Goshia [24]

The equation of the line with slope m and passing through the point $(x_0,y_0)$ is

$y-y_0=m(x-x_0).$

Since m=6 and the coordinates of the point are (8,3), then the equation is

$y-3=6(x-8).$

Answer: correct choice is B.

1/3+4/5= 17/15
The commun multipleof 3 and 5 is 15.
1/3×5= 5/15
4/5×3= 12/15
5/12+12/15= 17/12

Answer:

x = 130 degrees

Step-by-step explanation:

We know that the total angle equals to 180 degrees since it is a straight line

Therefore, 25 + 25 + x = 180

180 - 25 - 25 = 130

Therefore, x = 130 degrees
