Which expression is equivalent to 6m+(m-2)(m+7)+3

Vika [28.1K]

Answer:

$m^{2}$ + 11m - 11

Step-by-step explanation:

6m+(m-2)(m+7)+3 = 6m + [ m*m - 14 -2m + 7m] + 3

= 6m + mm - 14 + 5m + 3

= mm + 11m - 11

6m+(m-2)(m+7)+3 = $m^{2}$ + 11m - 11

David made a scale drawing of a mural he is going to paint. He used a scale of 1 cm=4ft. If the actual mural will be 16 feet lon

VikaD [51]

Answer:

4 cm

Step-by-step explanation:

we know that

The scale drawing is

$\frac{1}{4}\ \frac{cm}{ft}$

That means ----> 1 cm in the drawing represent 4 ft in the mural

To find out the dimensions in the drawing, multiply the actual dimension by the scale drawing factor

$(16\ ft)(\frac{1}{4}\ \frac{cm}{ft})=4\ cm$
