Factor completely:
4x²-49=

Use the Difference of Two Squares Formula,

If x² = 4x², then x = √4x², x = 2x

If y² = 49, then y = √49, y = 7

We know both x and y, straight to formula.

Therefore, the factored form of 4x²-49 is (2x+7)(2x-7)

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

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.
