The cost of a new house can be represented by the regression equation c = 120f + 90,000, where $120 is the cost per square foot and $90,000 is the cost of the lot. a new house on a lot costs $438,000. how many square feet does it have?

2900 square feet

Step by Step explanation:

you have to subtract 90,000 from the 438,000 then divide by 120 to find f.

24/56=hx^7

step-by-step explanation:

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
