PLEASE HELP >>> Given the following equations in vertex form, determine the number of real roots. (4 marks)

(a.) y = –2(x – 3)^2– 4

(b.) y = 5(x + 9)^2 – 6

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00

and then add them

  $50.00

+

  $15.00

+

    $3.00

$68.00

so sunghee has $68.00

make sure you have version 2.50

try looking in the very back of the book : )

step-by-step explanation:

you can download it here

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

i don't think there is enough
