Which function has real zeros at x = 3 and x = 7?
f(x) = x2 + 4x – 21
f(x) = x2 – 4x – 21
f(x) = x2 – 10x + 21
f(x) = x2 – 10x – 21

These question are hard can you me with answers

The line y = x + passes through (−3, 7) and is parallel to y = 4x − 1.

The expression 6x2 gives the surface area of a cube, and the expression x3 gives the volume of a cube, where x is the length of one side of the cube. find the surface area and the volume of a cube with a side length of 6m
