Answer:

4x^2+28x+49

Step-by-step explanation:

We have been given a perfect square trinomial 4x^2+...x+49. We are asked to fill in the missing blank.

We know that a perfect square trinomial is in form a^2+2ab+b^2.

We can rewrite terms of our given expression as:

2^2x^2+...x+7^2

(2x)^2+...x+7^2

We can see that the value of a is 2x and value of b is 7, so 2ab will be:

2ab=2(2x)(7)=28x

Since we are asked to give numerical answer, so the missing value is 28 for our given perfect square trinomial.

4x^2+28x+49

4x^2+14x+14x+49

2x(2x)+2x(7)+7(2x)+7(7)

2x(2x+7)+7(2x+7)

(2x+7)(2x+7)

(2x+7)^2

The missing term is 28.

It's A. Move the decimal to the right four places to make one the whole number, and then multiply one by ten to the negative fourth power to write it in scientific notation. If you're given a small decimal, the exponent will be negative. If you're given a large number, the exponent will be positive.
