Area of a square = Side × Side
Side = 7x-3
Area of the square = (7x-3) × (7x-3)
= 7x(7x-3) -3(7x-3)
= 49x^2 -21x -21x +9
=49x^2 -42x +9
Answer:

which is the first option in the list of possible answers.
Step-by-step explanation:
Recall that the minimum of a parabola generated by a quadratic expression is at the vertex of the parabola, and the formula for the vertex of a quadratic of the general form:

is at 
For our case, where
we have:

And when x = 1, the value of "y" is:

Recall now that we can write the quadratic in what is called: "vertex form" using the coordinates
of the vertex as follows:

Then, for our case:

Then, for the quadratic equal to zero as requested in the problem, we have:

3+/-11
add 11 to 3
11+3=14
minus 11 from 3
3-11=-8
the coordinate could be 14 or -8
Answer:
5² x 7 x 2
Step-by-step explanation:
350
= 35 x 10
= 7 x 5 x 5 x 2
= 5² x 7 x 2
