Answer 4

I'm sorry

Answer 5

find both areas by multiplying the binomials and then substract the pool's area to get the absolute area for which you will have to plug in the x value that is given

Answer 6

Thanks :)@kl0723

Answer 7

#1: (2x+6)(3x-2)
6x^2-4x+18x-12
6x^2+14x-12

#2 (3x-4)(x+3)
3x^2+9x-4x-12
3x^2-5x-12

Answer 8

now do #1-#2... you get the decks area

Answer 9

A(Deck)=
6x^2+14x-12-(-3x^2-5x-12)
6x^2+14x-12-3x^2+5x+12
3x^2+19x=?

Answer 10

Evaluate at x=4.75, A=to the nearest hundredth
3(4.75)^2+19(4.75)=?
157.94 units squared

Answer 11

@sammie2017 np ;)

Answer 12

@kl0723 ;p

Answer 13

@kl0723 is the expression for this problem: 3x^2+19x=?

Answer 14

that's your deck area

Answer 15

okay..just a little confused in the actual question it ask 2 questions
#1 Use the figure below to calculate the area of the deck
#2 Second, simplify the area if x=4.75. Round to the nearest hundredth.

then on my paper it ask for 2 answers
#1 the expression is:...............?
#2 the total square foot of the deck is........?
i know #2 is 158 just unsure of what to put for #1

Answer 16

@kl0723 i was thinking it meant the expression as in: 3x^2+19x=?

Answer 17

is not 158.... that is rounded to the nearest integer, you're being asked to give your answer to the nearest hundredth, and yeah #1 would be the expression for the deck's area before being evaluated

Answer 18

@kl0723 i must have read that wrong about rounding to the nearest hundredth. thanks for the help!
