Rewrite the expression without using grouping symbols. 13(19 – x) question 1 options: 1319 – 13x 13 • 19 – x 13 + 19 – 13 + x 13 • 19 – 13x

D. 13 * 19 - 13x

Step-by-step explanation:

To get your answer, you have to distribute 13 to both numbers inside the parenthesis. So it would be 13 * 19 - 13 * x. You don't need the multiplication sign between the 13 and the x to say that they need to be multiplied.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

none of these
