A = cross sectional area of the pipe. When the pressure is expressed in terms of the equivalent height of a column of that fluid, as is common with water, the friction loss is expressed as S, the "head loss" per length of pipe, a dimensionless quantity also known as the hydraulic slope.
Answer:
-4 and 4
Step-by-step explanation:
<u>Method 1</u>
Apply Difference of Two Squares Formula: 
Given 
Rewrite 16 as 4²
Therefore, 
and 
<u>Method 2</u>
Given equation:
Add 16 to both sides:
Square root both sides:
Therefore, x = -4, x = 4

Answer:
a).
= (67×10)÷2
= 670 ÷ 2
= 335
Explanation:
a).
= (67×10)÷2
= 670 ÷ 2
= 335
So, 5×67 = (67×10)÷2
=> 335 = 335
b).
= (67x2)+(67×2)
= 134 × 134
= 268
So, 5×67 ≠ (67x2)+(67×2)
=> 268 ≠ 335
c).
= (6 ×7)×5
= 42 × 5
= 210
So, 5×67 ≠ (6×7)×5
=> 210 ≠ 335
d).
= (5×6)+(5×7)
= 30 + 35
= 65
So, 5×67 ≠ (5×6)+(5×7)
=> 65 ≠ 335
<u>Hence</u><u>,</u><u> </u><u>(</u><u>a</u><u>)</u><u> </u><u>is</u><u> the</u><u> correct</u><u> answer</u><u>.</u>
