Answer:

(7x50)x4 = 1400

Step-by-step explanation:

It is given that (7 x 50 ) x 4

This is the form of associative property.

This can be expressed as, 7 x( 50 x 4)

Result  of both are equal.

That means we ca write,

(7 x 50 ) x 4 = 7 x( 50 x 4)

LHS = (7 x 50 ) x 4

RHS = 7 x( 50 x 4)

<u>Evaluate LHS</u>

LHS = (7 x 50 ) x 4  = 350 x 4 =1400

<u>Evaluate RHS</u>

RHS = 7 x( 50 x 4) = 7 x 200 = 1400

Therefore RHS ans LHS are equal

The graph of the function f(x) = (x + 2)(x - 4) is shown.
hoa [83]

Answer:

B)   All real values of 'x' where -2 < x< 4

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given function f(x) = (x +2 ) ( x-4)

                  (x+2)(x-4) =0

          ⇒  x +2 =0 and x-4=0

          ⇒  x =-2   and x=4

From graph

       Given parabola lies between the x=-2 and x =4

∴ All real values of 'x' lies between x=-2 and x =4

 All real values of 'x' lies -2 < x< 4

drek231 [11]
<h2>Answer:</h2>

Four points are always coplanar if:

A. They lie in the same plane.

C. all of them are collinear.

<h2>Step-by-step explanation:</h2>

<u>Coplanar--</u>

The points are said to be coplanar if all of them lie in the same plane.

<u>Collinear-</u>

The points are said to be collinear if all of them lie on a straight line.

Also as we know that a line always lie in one plane and so all the points that lie on that line will also lie in the same plane.

Hence, we may say that Four points will be coplanar if all of them are collinear.

      Hence, the correct options are:

         Option: A and Option: C
