Answer:

Kara incorrectly factored 2(16x^2 + 24x + 9) she did not find the correct factors when she factored out. The correct factored expression would be 2(4x+3)^2

Step-by-step explanation:

32x^2 + 48x + 18

2(16x^2 + 24x + 9)

2(16x^2 + 12x) (12x + 9)

2 4x(4x + 3) 3(4x + 3)

2(4x + 3)(4x + 3)

2(4x + 3)^2

Daniel can paint a house in 10 days, while his father can paint the same house in 6 days. If they work together, how long will t

Alex73 [517]

Answer:

3 $\frac{3}{4}$ days

Step-by-step explanation:

Let the amount of work be x.

Daniel:

10 days = x

1 day = $\frac{1}{10}$ x

Father:

6 days = x

1 day = $\frac{1}{6}$ x

Together:

1 day = $\frac{1}{10}$ x + $\frac{1}{6}$ x

= $\frac{6}{60}$ x + $\frac{10}{60}$ x

= $\frac{16}{60}$ x

= $\frac{4}{15}$ x

No. of days = $\frac{15}{15}$ x ÷ $\frac{4}{15}$ x

= $\frac{15}{15}$ x × $\frac{15}{4}$ x

= $\frac{225}{60}$

= 3 $\frac{3}{4}$
