Answer:
-4/9
Step-by-step explanation:
Answer:That is not the solution explanation: because if you put the 0 in place of the x in the equation, y would have to equal 6. If you put the -2 in place of the y then x would have to equal 8.
Simpler explanation: 0 + -2 = -2 not 6
The pro<span>bability of randomly pulling out a pineapple candy would be 5 over 8. Because there are 8 candies total (this is the denominator) and only 3 flavors, you just simply add the two given candies, which is 2 + 1 = 3, and subtract the sum (which is 3) by 8. Therefore, 8 - 3 = 5 and you put that as the numerator and the total number of candies, 8, as the denominator. </span>

Answer:
The length is 12metres, the width is 6metres
Step-by-step explanation:
Suppose the width is x, the length is x+6
The square is 72. The square of rectangular field is equal to product of length and width.
so x(x+6)=72
x^2+6x-72=0
a=1 b=6 c=-72
D= b^2-4ac= 6*6+288= 36+288= 324
sqrtD= 18
x1= (-b-sqrtD)/2a=(-6-18)/2= -12 (it is negative, but width is only positive. So this root doesn't match)
x2=(-b+sqrtD)/2a= (-6+18)/2= 12/2=6 - the width
The length is 6+6=12
