Answer and Explanation:
Given : Sides of right triangle 5,12 and 13.
To find : Show that the area of a right triangle of sides 5, 12 and 13 cannot be a square ?
Solution :
If 5,12 and 13 are sides of a right angle triangle then
13 is the hypotenuse as it is largest side.
then we take perpendicular as 12 and base as 5.
The area of the right angle triangle is

Here, h=12 and b=5



The area of the right angle triangle is 30 units.
30 is not a perfect square as 
There is no square pair formed.
Answer:
17.5% of 360 = 63
Step-by-step explanation:
We are given a process of finding 17.5% of 120. Following the same process we have to determine the 17.5% of 360.
17.5% can be break down as 10% + 5% + 2.5%
Thus,
STEP 1 : Find 10% of 360 , we get,

STEP 2 : find 5% of 360, we get,

STEP 3: find 2.5% of 360 , we get,

STEP 4: 17.5% of 360 = 10% of 360 + 5% of 360 + 2.5% of 360
⇒ 17.5% of 360 = 36 + 18 + 9
⇒ 17.5% of 360 = 63
7b-6(11-2b)=10
The first step is to distribute. Multiply each number inside the parentheses by -6.
7b + (-6*11) + (-6*-2b) = 10
7b - 66 + 12b = 10
Now combine like terms.
19b - 66 = 10
Add 66 to both sides.
19b = 76
Divide both sides by 19.
b = 4
The answer is b = 4.
