Laura wants to know the volume of her gold ring in cubic centimeters. She gets a rectangular glass with a base 7\text{ cm}7 cm7, start text, space, c, m, end text by 4.5\text{ cm}4.5 cm4, point, 5, start text, space, c, m, end text and fills the glass 8.8\text{ cm}8.8 cm8, point, 8, start text, space, c, m, end text high with water. Laura drops her gold ring in the glass and measures the new height of the water to be 9.2\text{ cm}9.2 cm9, point, 2, start text, space, c, m, end text.
What is the volume of Laura's ring in cubic centimeters?

which expression can be used to convert 80 us dollars (usd) to australian dollars (aud)?

1 usd = 1.0343 aud

1 aud = 0.9668 usd

step-by-step explanation:

sorry just need the points

understand that i don't know the answers

will someone answer his question

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!
