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
Step-by-step explanation:
x = 47, m∠3 = 56°like this question
Original equation
<span>√x+10-9 = -7
</span>Isolate
<span>√x+10 = 9-7
</span>
<span>√x+10 = 2
</span> Raise both sides to the second power
<span> (√x+10)2 = (2)2
</span> After squaring
<span> x+10 = 4
</span>
x + 6 = 0
so the answer is x=-6

1) division
2) m - 5 . Since subtraction is not commutative.
