Divide $1750 into two parts so that simple interest on the first when deposited for 2 years at 15% per annum that on the second when deposit for 3 years at 66% per annum in the bank add to to live the total interest of $624.​

Step-by-step explanation:

X*2*15+(1750-x)*66*3=624

30x+34650-198x=624

168x=34650-624

X=202,5

1750-202,5=1547,5

the answer is a

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!
