At the elementary school, the fourth graders Jamal and Dinah are still eating lunch as they come into math class. Someone has left a book on the floor and they both trip. As they each hit the floor, the food they are carrying flies across the room directly toward Harold, who is showing off his latest dance moves. As Jamal and Dinah watch in horror, Jamal’s cupcake and Dinah’s sandwich splat right on top of Harold’s head! Jamal’s cupcake flies on a path that would have landed on the floor 22 feet away from him if it had not hit Harold. Dinah’s sandwich flies on a path that would have landed on the floor 26 feet away from her if it had not hit Harold. Jamal’s cupcake flies 8 feet high, while Dinah’s sandwich reaches a height of 5 feet before hitting Harold.

How tall is Harold? Once you have the equations, you may use Desmos to help find the answer.

This question uses a numeric answer. Type in just the number part answer (no letters!) and round to 2 decimals.

3, 12, 48, 384, 1536, 6144, 24576, 98304

step-by-step explanation:

just keep timing it by 4.

answer: x=3 and y=4

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!
