Which ratio correctly compares 30 in. to 2 ft, when the lengths are written using the same units?
note: 12 in. = 1 ft
a. 1: 15
b. 5: 45
c. 4: 5
d. 15: 1

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

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
