Select ALL the correct answers.
IgorC [24]

Answer:

A. 4(x - 4) + 2(3x² + 3x - 20)

C. (11x² + 7x - 55)-(5x² - 3x + 1)

F. (3x² + 5x - 28) + (3x² + 5x - 28)

Step-by-step explanation:

Given:

(3x-7)(2x+8)

= 6x² + 24x - 14x - 56

=6x² + 10x - 56

A. 4(x - 4) + 2(3x² + 3x - 20)

= 4x - 16 + 6x² + 6x - 40

= 6x² + 10x - 56

B. (3x² + 5x - 28) - (2x² + 4x + 28)

= 3x² + 5x - 28 - 2x² - 4x - 28

= x² + x - 56

C. (11x² + 7x - 55)-(5x² - 3x + 1)

= 11x² + 7x - 55 - 5x² + 3x - 1

= 6x² + 10x - 56

D. 4(x - 4) - 2(3x² + 3x - 20)

= 4x - 16 - 6x² - 6x + 40

= - 6x² - 2x + 24

E. (11x² + 7x - 55)-(5x² - 3x + 2)

= 11x² + 7x - 55 - 5x² + 3x - 2

= 11x² - 5x² + 7x + 3x - 55 - 2

= 6x² + 10x - 57

F. (3x² + 5x - 28) + (3x² + 5x - 28)

= 3x² + 5x - 28 + 3x² + 5x - 28

= 6x² + 10x - 56

Convert 17.42 m to customary units. A.57'-17/8" B. 36-10 1/2" C. 442 1/2" D. 367/8" E. None of these answers is reasonable.
Allushta [10]

Answer:

E. None of these answers is reasonable.

Step-by-step explanation:

Customary units are inches, feet, yards, and miles.

Since,

1 foot = 0.3048 meters,

⇒ 1 meter = \frac{1}{0.3048} feet,

17.42 meters = \frac{17.42}{0.3048} feet

=\frac{174200}{3048}\text{ feet}

=57\frac{ 464}{3048}\text{ feet}

=57\frac{58}{381}\text{ feet}

Now, 1 feet = 12 inches,

⇒ \frac{58}{381} feet = \frac{12\times 58}{381} inches

= \frac{232}{381}\text{ inches}

Hence,

17.42 meters = 57\text{ feet }\frac{232}{381}\text{ inches}

= 57' 232/127''

That is, None of these answers is reasonable.
