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

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

what are ur choices?
