(5a) + 4 > (3a) + 10

If the length of the things doesn’t matter then I’d leave it as

5a + 4 = 3a + 10

Hope this helps :)

What is the factored form of the expression? 16b^2 – 81

solong [7]

Answer:

(4b-9) (4b+9)

Step-by-step explanation:

16b^2 – 81

This is the difference of squares

(a^2 -c^2) = (a-c) (a+c)

a^2 = 16b^2 so a= 4b

c^2 = 81 so c = 9

(16b^2 – 81) = (4b-9) (4b+9)

how many square meters of tile are needed to tile the sides and bottom of the swimming pool that's 25 by 20

Burka [1]

The bottom is (25 x 20) = 500 of whatever those units are, squared. Each long side is (25 x the depth of the pool, which we don't know), and each end is (20 x depth).
