Find Sp if Mp: Rs 650 & dis 2.5%

Mp= Rs 650

Dis= 2.5

Sp=?

Now,

Dis=Mp-Sp

Sp=Mp-Dis

=650-2.5

=647.5

answer is 633.75 Rs.

Step-by-step explanation:

650- 2.5/ 100× 650 650-16.25 = 633.75 RS. the selling price of the item is 633.75 Rs

answer: 590

step-by-step explanation:

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!
