To solve for this we need x by itself. To do that we divide both sides by 5.
This will leave you with x <_9.
D. Heptagon
A decagon has 10 sides
an octogon has 8 sides
a pentagon has 5 sides
a heptagon has 7 sides which in turn leaves you with your answer
plz mark brainliest hope this helps and have a nice day:)
Shaded raea = area of circle - area of hexagon
area of circle = pi r^2 = 36pi
area of hexagon = 3 sqrt3 * a^2 / 2 where a = length of each side
To find a:-
consider the triangle with vertex angle = 60 and 2 sides enclosed by 2 sides of length 6 this is an equilateral triangle so a = 6
so, area of hexagon = 3*sqrt3* 6^2 / 2 = 93.531 cm^2
Area of shaded region = 36 pi - 93.531 cm^2
= 19.57 cm^2
In the graph is shown: x-axis is the hours that student spend studying for the test and y-axis is a grade obtained by student. The best fit equation is y=3.75x+52.5.
If student spend 0 hours, then x=0 and y=3.75*0+52,5=52.5. It is that the student most likely earn <span>grade of 52.5 in the test. </span>
To find the value of x, isolate the x first,
5x + 6 = 2x +15
Subtract 6 to both sides because whatever you do on one side you would always to on the other side.
5x = 2x + 9
Subtract 2x from both sides
3x = 9
Divide to isolate the x
x = 3 is your answer
