If you want the strip around the mat:
x=strip of mat
2(20+2x)+2(15+2x)=102
Distribute
40+4x+30+4x=102
Combine like terms
70+8x=102
Subtract 70
8x=32
Divide by 8
x=4
If you want the whole width of the mat:
w=15+x
w=15+2*4
w=23
Answer: 20.5
Step-by-step explanation:
From the measure of the length of the sides of the triangle, 9, 40 and 41 we can infer that the triangle is a right angled triangle. 9-40-41 is a Pythagorean triplet.
In a right angled triangle, the circumradius is half the hypotenuse.
In the given triangle, the hypotenuse = 41.
Therefore, the circumradius is 41÷2= 20.5 units.
Step-by-step explanation:
Some of the property of log are as follows :
1. 
2. 
3. 
Now coming to question,
(a) 
(using property 1)
(b) 
(using property 2)
(c) 
(using property 3)
Hence, this is the required solution.
1. In each graph, the two lines are parallel to each other.
2. Each set of equations have the same slope.
3. Equations that have the same slope as each other will always be parallel to each other.
You have to distribute it.
EXPLANATION:
13 pt 13-p
13-13
0 pt-p
-p-0
-p= 14
14 pt
= 14
