Two numbers have a sum of 9 when added together. the same two numbers have a product of 20 when multiplied together. complete the table and write a system of equations to represent the two numbers.

Step-by-step explanation:

If we call one number and the other , we have the equations:

(the sum of the numbers is 9)

(the product of the numbers is 20)

This would be the system of equations corresponding to the situation described.

the solutions to the system are

and

because

(these values can also be found by clearing a variable from the first equation and substituting in the second one)

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

answer: answer: d) v= 1/6 bh
