Write x^2 - 6x + 7= 0 in the form (x-a)^2 b, where a and b are intergers.

dimaraw [331]

Answer:

(x-3)^2=2

Step-by-step explanation:

${x}^{2} - 6x + 7 = 0 \\ adding \: 2 \: both \: sides \\ {x}^{2} - 6x + 7 + 2 = 0 + 2 \\ {x}^{2} - 6x + 9 = 2 \\ {x}^{2} - 6x + {(3)}^{2} = 2 \\ (x - 3) ^{2} = 2$

sergiy2304 [10]

Answer:

B

Step-by-step explanation:

The sections of the parallel roads split by the transversals are in proportion, that is

$\frac{350}{300}$ = $\frac{first}{1650}$ ( cross- multiply )

300 first = 577500 ( divide both sides by 300 )

first = 1925 ft

Thus

Elm st → Maple st = 1925 + 350 = 2275 ft → B
