Find the square. (6m 7)^2 a. 36m^2 84m 49 b. 36m^2 84m – 49 c. 36m^2 42m – 49 d. 36m^2 – 84m 49

Option a 

Option d

Step-by-step explanation:

Given : Expression -

To find : The square of the given expression

Solution :

We have to solve  

Apply property :

In the given expression

a=6m, b=7

The solution is

Therefore,

If the sign is '+' then Option a is correct.

If the sign is '-' then Option d is correct.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
