Alena had 4 packs of gum with 6 pieces of gum in each pack. Hugh had 3 packs of gum with 5 pieces in each. Alena and Hugh have 19 pieces of gum left. Which equation can you use to find p, the number of pieces of gum Alena and Hugh chewed? A) 19-(4•6)+(3•5)=p
B) (4•6)+(3•5)-19=p
C) 19-(3+4)•(6+5)=p

B) ( 4 * 6 ) + ( 3 * 5 ) - 19

Step-by-step explanation:

As per the given information

Alena - has a total of 4 packs of gum, with 6 pieces each

          - so she has a total of  4 * 6 = 24

Hugh - has a total of 3 packs of gum, with 5 pieces each

         - so he has a total of 3 * 5 = 15

Add the two of them up to find the total amount of gum they have

Alena + Hugh

= ( 4 * 6 ) + ( 3 * 5 )

They have 19 pieces left

So the total amount they have, minus 19 will yield the amount they chewed.

Hence:

Alena + Hugh -19

= ( 4 * 6 ) + ( 3 * 5 ) - 19

That is option B

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
