Answer is x=-2 hope that helps
Given
Area of the regular pentagon is 6.9 cm².
Find out the perimeter of a regular pentagon
To proof
Formula
Area of regular pentagon is
As given in the question
area of regular pentagon = 6.9 cm²
now equating the area value with the area formula.
Now put
√5 = 2.24 ( approx)
put in the above equation
thus
a² = 4.01
a = √ 4.01
a = 2.0 cm ( approx)
As perimeter represented the sum of all sides.
i.e regular pentagon have five sides of equal length.
Thus
perimeter of the regular pentagon = 5 × side length
= 5 ×2.00
therefore the perimeter of the regular pentagon = 10cm
option c is correct
Hence proved
Answer:
a
Step-by-step explanation:
its graph point is mistake
Answer:
She moved 3 to the left and 5 down.
She could have calculated each point seperately.
A(1,-1) then subtract 2 and subtract 6 from the x and then the y-coordanate, which gets you to A'(-1,-7). Then, do this with every other coordanate and you will get your answer. Hope this helped!
x-intercepts are points of the form (x, 0), and y-intercepts are points of the form (0, y).
You find the x-intercepts by solving for x such that y = f(x) = 0:
You know x - 6 is a factor of f(x), which means x = 6 is a solution to the above equation, and that means that (6, 0) is one x-intercept.
You can find the other two by dividing f(x) by x - 6 (i.e. further factorizing f(x)).
So we have
and this means the x-intercepts are (6, 0), (2, 0) and (1, 0).
The y-intercept is easier to find; set x = 0, then solve for y = f(0):
and so the y-intercept is (0, -12).
