Kaylee is building a rectangular enclosure with an area of 90 square yards. she
wants the length of the enclosed area to be 6 yards longer than the width, x.
to represent this, she writes the equation x2 + 6x = 90. she then completes the
square to solve her equation for x.
which equation is equivalent to kaylee's equation after she completes the square?

ok

step-by-step explanation:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

no
