Step-by-step explanation:
5x^2+2x=1
5x^2+2x-1=0
x=-b+/-√b^2-4ac÷2a
x=-2+/-√-2^2-(4×5×-1)÷2×5
x=-2+/+√4--20÷10
x=-2+/-√24÷10
x=-2+√24÷10 or -2-√24÷10
x=-2+4.9÷10 or -2-4.9÷10
x=2.9÷10 or -6.9÷10
x=0.29 or -0.69
Answer:
17.66m
Step-by-step explanation:
Let the area of the rectangular garden be L²
A = L²
19.5 = L²
L = √19.5
L = 4.416
Perimeter = 4L
Perimeter = 4(4.416)
Perimeter of the garden =17.66m
Hence the number of meters of fencing that are needed to go around the garden is 17.66m
12 + 8 = 20 Omar has 20 points now
3 - 1 = 2
1/4 - 3/16 = 4/16 - 3/16 = 1/16
answer is : 2 1/16 (in mixed number) or 33/16 (in improper fraction)
