Step-by-step explanation:
Hey there!
Standard form is what this equation is in
Standard form is this: 
So order to complete the square, you need to take the
term out of the equation, divide it by two, and then square it
In this case, the
term is 8
We need to divide 8 by 2 ---> 4
Then square 4 ---> 16
So now you should add 16 to both sides

Now you can simplify the LHS

Now you subtract 16 from both sides

So this is as far as you can go since you cannot take the square root of a negative number
If 150g of fertilizer can cover 6 sq m of land then, 25 g of fertilizer can cover 1 sq m of land;
a)
For 13 sq m of land we need 25g*13
325g
b)
850g/25g=amount of land
34 sq m

The probability of not receiving a salad is 5/9
Step-by-step explanation:
There are 3 different types of hamburgers, 2 chicken sandwiches, and 4 types of salads.
Hence total number of choices are 2+3+4= 9
Since, we have 4 choices of salad, hence probability of receiving a salad is given by

Hence, the probability of not receiving a salad is given by

Therefore, the probability of not receiving a salad is 5/9
