Which equation is true? O (8.4 x 10') + (3 x 10°) = 8,700,000
O (8.4 x 10°) – (3 x 10') – 8.100
O (8.4 x 10'). (3 10”) – 25.2
O (8.4 x 10') : (3 x 10°) - 280

answer: i realy don't get it that much can you me figer it out pleas you

step-by-step explanation:

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.

thats not a system of equations, that is a solution
