Answer:
(i) a = 2
b = -1
c = -1
(ii) x= 1
Step-by-step explanation:
<u>Step 1: Factorise</u>
<u>Step 2: Use the complete square method. </u>
<u>Step 3: Have it</u><u> </u><u>to </u>
<u>Line of symmetry: </u>
To find line of symmetry, we use -b/2a formula.
Based from 
:
a=2, b=-4
-b/2a = -(-4)/2(2) = 1
That would be B
|-6| + |4| = 6 + 4 = 10
Answer:
12
Step-by-step explanation:
1/2(x^2 + x) x=4
1/2(4^2+4)
1/2(16+4)
1/2 x 20

Answer:
28.2 ft²
Step-by-step explanation:
Data provided in the question:
Length of the display floor, l = 4.7 feet
Width of the display floor, w = 6 feet
Therefore,
The area of the floor space = l × w
on substituting the value in the above formula,
The area of the floor space = 4.7 × 6
or
The area of the floor space = 28.2 ft²
Hence, the floor space needed for the display is 28.2 ft²
