Answer:
The area is 81 mm^ 2 or 81 mm squared
REMEMBER TO PUT THE UNIT
Step-by-step explanation:
Area of a sqaure is s^2 or s x s
First you need to know the perimeter, 36 mm
Each side is 9 mm because 36/4 is 9.
Then Substitute and calculate:
s^2
9^2
81 mm squared
OR
s x s
9 x 9
81 mm squared

Answer: Addition Property
Step-by-step explanation:
The difference between steps one and two is that the -9 is added to the other side to isolate 5x. (added- addition property)
60% = 372
----------------------------------------------
Find 1 %
----------------------------------------------
60% = 372
1% = 372 ÷ 60
1% = 6.2
----------------------------------------------
Find 100%
----------------------------------------------
1% = 6.2
100% = 6.2 x 100
100% = 620
--------------------------------------------------------------------------------------------
Answer: There are 620 students in the school.

The value of x is equal to 1.5.
It is required to find x.
<h3>What is quadratic equation?</h3>
Any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power. The quadratic formula to solve a quadratic equation ax2 + bx + c = 0 is x = [-b ± √(b2 - 4ac)]/2a.
Given that:
So for the triangle, the perimeter would be:
By solving in above equation, we get
So, we take x= 1.5 and neglect -4 because we can't take negative roots of the quadratic equation.
Hence, the value of x is equal to 1.5.
