Answer:

8x^2 + 24x - 14

Coefficients:- a =  8, b = 24 and c = -14.

Step-by-step explanation:

(4x - 2)(2x + 7)

= 4x(2x + 7) - 2(2x + 7)

= 8x^2 + 28x - 4x - 14

= 8x^2 + 24x - 14

Coefficient a =  8, b = 24 and c = -14.

BigorU [14]

The algebraic expression is:8(x+4)=3

And Value of x is: x=\frac{-21}{8}

Step-by-step explanation:

We need to write the expression of the statement:

Eight times the sum of a number and 4 equals 3

Let the number = x

The expression will be:

8(x+4)=3

Solving the expression to find value of x:

8(x+4)=3\\8x+24=3\\Adding\,\,-24\,\,on\,\,both\,\,sides:\\8x+24-24=3-24\\8x=-21\\x=\frac{-21}{8}

So, The algebraic expression is:8(x+4)=3

And Value of x is: x=\frac{-21}{8}
