Solve the equation 36x^2 25=0

Anna71 [15]

Would assume it to be 36x² - 25 = 0

36x² - 25 = 0

(6x)² - 5² = 0

(6x + 5)(6x - 5) = 0 By difference of two squares.

6x + 5 = 0 or 6x - 5 = 0

6x = -5 6x = 5

x = -5/6 x = 5/6

x = +5/6 or - 5/6

The equation d = 3t gives the distance, d, in meters that Liam swims with respect to time, t, in seconds.

Natasha_Volkova [10]

Answer:

Liam's rate = 3 meters per second

Edgar's rate = 3.2 meters per second

Edgar swims faster

Step-by-step explanation:

Liam:

The equation $d=3t$ gives the distance, d, in meters that Liam swims with respect to time, t, in seconds.

When $t=0,\ d=0.$

When $t=1,\ d=3.$

Rate of change:

$\dfrac{3-0}{1-0}=3$

Liam's rate is 3 metres per second.

Edgar:

When $t=20, \ d=64.$

When $t=40,\ t=128.$

Rate of change:

$\dfrac{128-64}{40-20}=\dfrac{64}{20}=3.2$

Edgar's rate is 3.2 metres per second.

Edgar swims faster.
