Using number line and mental mathematics, the value of u = -√25, t = - 2π, s = -√68
<h3>What is a number line?</h3>
A horizontal line with evenly spaced numerical increments is referred to as a number line. How the number on the line can be answered depends on the numbers present.
The usage of the number is determined by the question that it corresponds to, such as when graphing a point.
As we can observe that
All the points lie on negative axis. The value of u = -√25 = 5
t = -2π = -2×3.14 = -6.28
s = -√68 = - 8.24

Given that the contaminated region is a square, the area is given by the formula:
Area=length*width
since in a square length=width
the
area=length×length
or
area=width×width
thus given that area=4m^4/144n^4 sq. units let the width be w units
thus
area=w×w=4m^4/144n^4
w²=4m^4/144n^4
solving for w we get:
w=√(4m^4/144n^4 )
w=2m²/12n²
Hence the width,w=2m²/12n²
Answer:
13cm
Step-by-step explanation:
P=2l+2w
56=2(15)+2w
56=30+2w
26=2w
w=13
Answer:
-6
Step-by-step explanation:
10--6=16
10+6=16
Answer:
5/2
Step-by-step explanation:
5/2 because 2/5 times 4 is 8/2 plus 1/2 is 9/2
