Answer:
86 units squared.
Step-by-step explanation:
If the perimeter is 30 and it is an equilateral triangle, the means each side of the triangle is equal so they must all be 10 units longs. Since the line XA is part of the quadrilateral, lines FL and XA of the rectangle must be 10 units long. But we still don't know the length of the sides. Within the box are two right triangles, FZX and ZLA. We know the the length of the hypotenuse which is 10 units, and the base which is 5 units. Then we use the Pythagorean Theorem so find the length of the sides. After we do that we get about 8.6. Now we can multiply the length and width to get an area of 86.
Answer: 130
Step-by-step explanation:
so 0.7x + x = 221
so 1.7x = 221
divide both sides by 1.7 to get
x = 130
Answer:
It is not a Function
Step-by-step explanation:
There are multiple x-values that are repeating in the relation. If we did the vertical line test, it will fail because the line would touch two parts of the graph.
The relation is not a function.
First we write equation for perimeter of rectangle. Why? because we have been given that it is 128 units and maybe we can calculate something from it.
P = 2a + 2b where
a = 2(3y + 1 ) and b = 2(2y +3)
P = 6y + 2 + 4y + 6 = 10y + 8 = 128
now we can solve for y
10y = 120
y = 12
Now we just express value of y in formula for finding lenght of VW and we got length
Answer is 37
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
