The o'brien's are building a rectangular deck around the outside of their circular pool. a.) find the combined area of the deck and the pool if the deck is (2x + 3) units wide by (5x + 6) units long. (a =lw) show all work. b.)if the area of the pool is 3x^2 + 7x + 6, what is the area of just the deck?

A:

Width of the deck = units

Length of the deck = units

So area of rectangular deck = Length * width

=

Area =

Area= units square

As mentioned in part B, the area of the pool is so the combined area of the deck and pool is

Area = area of rectangular deck + area of pool

= unit square

B:

The area of only the deck is unit square

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
