Answer:

expand (a + 7) * 2:   2a + 14

Step-by-step explanation:

(a + 7) * 2

= 2 ( a + 7)

apply the distributive law:     a(b + c) = ab + ac

a = 2, b = a, c = 7

= 2a + 2 * 7

multiply the numbers:   2 * 7 = 14

= 2a + 14

A seal went 25 feet below sea level to catch a fish. A sea lion dove 10 feet less than three times as deep as the seal to catch
vfiekz [6]

Answer:

65 feet below sea level.

Step-by-step explanation:

With the information provided, we can create the following equation for the position of the sea lion (p)

p = 3x - 10

In this equation, x would be the final position of the seal when it caught the fish. Since we are told that the seal's position is 25 feet below sea level then we can plug in this value as x and solve for p...

p = (3 * 25) - 10

p = 75 - 10

p = 65

Finally, we can see that the sea lion's position is 65 feet below sea level.
