You're looking for an inequality of the form |t-b|\le a, or -a\le t-b\le a, or b-a\le t\le b+a.

Start with

350^\circ\le t\le400^\circ

Notice that 375º is the midpoint of this interval of temperatures. If we subtract all sides by 375º, then we get

-25^\circ\le t-375^\circ\le25^\circ

so we can set a=25^\circ and b=375^\circ, and we can rewrite this inequality in terms of absolute values as

|t-375^\circ|\le25^\circ

Which of the following constants can be added to x2 + x to form a perfect square trinomial?
solmaris [256]

The constant should be added to form a perfect square trinomial will be 1/4. Then the correct option is D.

<h3>What is a quadratic equation?</h3>

It's a polynomial with a value of zero. There exist polynomials of variable power 2, 1, and 0 terms. A quadratic equation is an equation with one statement in which the degree of the parameter is a maximum of 2.

The expression is x² + x.

Then the constant should be added to form a perfect square trinomial.

Then the constant will be

The square of the half of the coefficient of the variable x is to be added to make a perfect square.

Then the constant will be 1/4.

Then the perfect square will be

\rm \rightarrow x^2 + x + \dfrac{1}{4}\\\\\\\rightarrow x^2 + 2 \times \dfrac{1}{2} x + \left (\dfrac{1}{2} \right )^2\\\\\\\rightarrow \left (x + \dfrac{1}{2} \right)^2

More about the quadratic equation link is given below.
