Solve 15+6-(9+2)•4 solve using the order of operation

=-23

Step-by-step explanation: This question it's going to be PEMDAS. p-parenthesis, e-exponents, m-multiply, d-divide, a-add, s-subtract. It can also go left to right. We start with (9+2) parenthesis and it give us equal to 11. To multiply and you must go left to right. This give us equal to 44, so add and subtract must go left to right. Now, to add left to right and equal to 21, and subtract this give us equal to -23.

Hope this helps!

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.
