On a winter morning, the temperature In Pittsburgh Is -13°F and the temperature in Cleveland Is-10°F. On the same morning, the temperature in Chicago is higher than the temperature in Pittsburgh. Which statement explains what the temperature in Chicago could be?

-12°F o -11°F.

Step-by-step explanation:

We have two statements, which are the following:

- the temperature In Pittsburgh Is -13 ° F

- the temperature in Cleveland Is-10 ° F

Then they tell us, "the temperature in Chicago is higher than the temperature in Pittsburgh"

Which means that the statement that helps us is the first, which is the one that tells us about Pittsburgh, now, a higher number since it is a higher temperature, we know that when a number is negative, the higher the number is , actually the number is less, therefore the temperature should be at least -12 ° F or -11 ° F. That is, anyone with sense between the city's temperature ranges greater than -13.

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
