Answer:
see the explanation
Step-by-step explanation:
Let
L ---> the length of rectangle in cm
W ---> the width of rectangle in cm
The area of rectangle is
so
---> equation A
we know that
<u><em>Prime numbers</em></u> only have factors of 1 and themselves.
So a rectangle with an area of 991 cm² can only be either
or
I belive this would be B.
Attached is what goes with y=3(1/2)^x
Hope this helps!
Answer:
90-54w
Step-by-step explanation:
use the distributive property
1) A. since, if you put the numbers into the equation (one at a time) the equation = 0 each time, which is true.
2) I think I've been taught to complete the square slightly differently
x^2 - 18x - 17 = 0
(x-9)^2 - 81 -17 = 0
(x-9)^2 - 98 = 0
I hope you can get something from that
