Let's solve ~




It's factorized now ~ And if you want to find the zeros then equate the expression with 0.
And you will get ;

D: 17, it is further from the mean than any other number by far.
to solve for the dimensions (x+7)(x+2)=66,
we can first use the foiling method to simplify the left side.
x^2 + 2x + 7x + 14 = 66
x^2 + 9x + 14 = 66
now, subtract 66 from both sides.
x^2 + 9x - 52 = 0
now, split this into two parentheses.
(x + 13)(x - 4)
since the root of -13 would give you negative values, x=4. This means that the dimensions of the rectangle are 11 and 6.
The answer is D
I’m right trust
