Answer: 6units
Step-by-step explanation:
Since it is a regular polygon, and it has 3 equal sides it means the polygon is a quadrilateral.
From the diagram,
5 - 2x = -4x + 9 ( side of quadrilateral )
Solving for x in the equation
-2x + 4x = 9 - 5 ( collection of like terms in simple linear equation )
2x = 4
Divide through by the coefficient of x which is 2
x = 2.
Therefore, the perimeter of the polygon which equals to the total length of the polygon is
Perimeter = 2 + 2 + 2
= 6units
The answer to this question is C
Answer:
am not sure to but i think it should be 65 degree
This is a problem on addition of dissimilar fractions.
1/3 + 3/5 = ?
To add dissimilar fractions, we have to convert it first to similar fractions. To convert to similar fractions, find the Least Common Multiple (LCM) of the denominators. In this case, LCM is 15. Then rewrite the fractions using the LCM as the denominator.
1/3 = 5/15; 3/5 = 9/15
Now proceed with the addition -
5/15 + 9/15 = 14/15
Then subtract the sum from the savings -
1 - 14/15 = 1/15
Therefore, Rachel still has 1/15 of her savings
