Holly has a rectangular garden that measures 12 m wide by 14 m long. She wants to increase the area to 255 m² by increasing the width and length by the same amount. What will be the length (longer dimension) of the new garden? Enter your answer in the box.

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

to determine the unit cost your would divide the total cost by the number sold.
