Answer 2

Answer:

>> Given:

Value of x :

= 5

>> To find:

The value of :

6 - 7x²

>> Concept:

First find the square of x .

Then multiply the square of x with the 7 and then subtract it with 6.

>> Solution:

\Rightarrow{6-7x²}⇒6−7x²

\Rightarrow{6-7×(5)²}⇒6−7×(5)²

\Rightarrow{6-7×(5×5)}⇒6−7×(5×5)

\Rightarrow{6-7×25}⇒6−7×25

\Rightarrow{6-175}⇒6−175

\Rightarrow{-169}⇒−169

>> Answer:

So , the value of 6-7x² is -169 .

>> Extra information:

Area of the square:

As=S×SAs=S×S

Where,

As = Area of the square

S = One side of the square

Area of the rectangle:

Ar=L×BAr=L×B

Where,

Ar = Area of the rectangle

L = Length

B = Breadth

Area of the triangle:

At=\frac{H×B}{2}At=2H×B

Where,

At = Area of the triangle

H = Height

B = Breadth
