Answer:
x = -2
y = 8
Step-by-step explanation:
8x + 5y = 24
y = -4x
8x + 5 (-4x) = 24 (Substitute y value)
8x - 20x = 24 (Multiply)
-12x = 24 (Combine like terms and divide)
x = -2
y = -4 (-2) (Substitute x value. Multiply)
y = 8
Okay so I have looked at this and I think I know how to do it...
since its an irregular shape you need to section it into shapes, so for this you have a square and a rectangle.
So lets start with triangle... (base × height)/2
It looks like the base of the triangle is the side that says 12 for the whole shape.
Subtract 5 from 12 you get 7 so the base is 7
The Height is 5
So your equation is...
(7 x 7)/2
(49)/7
7
Next is the square... a^2
5 x 5
25
Add them together...
7 + 26 = 32
And you get your area of 32
Hope this helps!
Answer:
To find the measure of an interior angle of a regular polygon, take the sum of all interior angles and divide by the number of angles. The sum of all interior angles can be found by (n - 2)*180 where n is the number of sides, in this case 24. So all the interior angles add to 3960 degrees.
PLEASE SAID THANKS
That length is the distance between (-4, 5) and (3, 2), computed using the Pythagorean theorem as
.. √((5 -2)^2 +(-4-3)^2) = √(9+49)
.. = √58
.. ≈ 7.616
