PLEASE HELP!!: For Questions 6 and 7, determine whether each pair of triangles is similar. Justify your answer.

6.   Not similar

7,   Are similar

Step-by-step explanation:

In problem 6 one triangle is a SSA situation and the other triangle is SAS, we  cannot say the triangles are similar.

In problem 7, both triangles are a SAS situation, so we need to see if corresponding sides are in proportion.

Is 10/25 = 18/45?

10/25 = .4  and 18/45 = .4

Therefore, the triangles are similar

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!

what is the your question?
