I must assume that you meant   <span>X^2-10x =7.  If that is indeed the case, then:

</span>X^2-10x =7  =>  x^2 -10x + 25 - 25 = 7, so that (x-5)^2 = 32  (Add 25, then 
                                                                                                 subtract 25)
Then x-5 = plus or minus sqrt(16)sqrt(2) = 4sqrt(2).

Then x = 5 plus or minus 4 sqrt(2) (answers)

The square below has an area of 1+ 2x + x² square meters.
Brums [2.3K]

Answer:

1 + x  meters.

Step-by-step explanation:

A square has 4 equal sides so each side will have a length equal to the square root of the area.

Side length = √(1 + 2x + x^2)

                   = √(1 + x)(1 + x)

                   = 1 + x.
