ANSWER

$12 \sqrt{5}$

EXPLANATION

The given expression is

$\sqrt{2} \times \sqrt{72} \times \sqrt{5}$

The middle radical contains a perfect square.

$\sqrt{2} \times \sqrt{36 \times 2} \times \sqrt{5}$

$\sqrt{2} \times \sqrt{36} \times \sqrt{2} \times \sqrt{5}$

$6\sqrt{2} \times \sqrt{2} \times \sqrt{5}$

Note that:

$\sqrt{a} \times \sqrt{a} = a$

$6\times 2 \sqrt{5} = 12 \sqrt{5}$

The tile along the edge of a triangular community pool needs to be replaced.

Gre4nikov [31]

Answer:

Third option: 12x^2+8x+25

Step-by-step explanation:

s1=8x^2

s2=4x^2+15

s3=8x+10

Total perimeter of the pool edge: P

P=s1+s2+s3

Replacing s1, s2 and s3 in the formula above:

P=(8x^2)+(4x^2+15)+(8x+10)

P=8x^2+4x^2+15+8x+10

Adding like terms:

P=12x^2+8x+25

MrRissso [65]

Answer:

First, break the shape into smaller shapes.

Bigger rectangle: 5m, 8m

Thin rectangle: 7m, 3m

Thinner rectangle: 8m, 2m

We will call the bigger rectangle B, the thin rectangle R, and the thinner rectangle r.

Step-by-step explanation:

B = 8 • 5 = 40

R = 7 • 3 = 21

r = 2 • 8 = 16

Add the areas together:

40 + 21 + 16 = 77

Therefore, the area is 77 meters.
