Answer:
25 lb bag of fertilizer can cover <u>10 square feet</u> of lawn.
Step-by-step explanation:
Given:
5 pounds of fertilizer cover = 2
of the lawn
We need to find the 25 lb bag cover.
Solution:
Now we know that;
5 pounds of fertilizer = 2
of yard.
1 lb of fertilizer = Number of
lawn covered by 1 lb fertilizer.
Using Unitary method we get;
Number of
lawn covered by 1 lb fertilizer = 
Now we can say that;
1 lb of fertilizer =
of the yard
25 lb of fertilizer = Number of
lawn covered by 25 lb fertilizer.
Again by using Unitary method we get;
Number of
lawn covered by 25 lb fertilizer. = 
Hence 25 lb bag of fertilizer can cover <u>10 square feet</u> of lawn.
19 + 8 = h/3or h/3 = 27Multiply both sides by 3h = 27*3 = 81

Answer:
p = 4
Step-by-step explanation:
Given the expression x ^ 2-px + 3 = 0
If x = 0 is a solution
Substitute into the expression
0² - 0p + 3 = 0
-0p = -3
p = 3/0
p cannot be determined for this root
If x = 1
1² - 1p + 3 =0
1 - p + 3 = 0
-p+4 = 0
-p = -4
p = 4
Hence the va;ue of p is 4
