For 13. just add all the sides.
4 + 21 + 23 + 7 + 9 = 64
For 14. multiply width and height of both shapes then add them together.
1.7 x 5.2 = 3.74 ( rectangle area )
3.0 x 3.0 divided by 2 = 4.5 ( triangle area )
Add the two answers
3.74 + 4.5 = 8.24
I honestly dont know how to figure this one out.
Yo sup??
in the given figure
9y-3=69
9y=72
y=8
now by angle sum property
9y-3+69+5x+2=180
5x=40
x=8
Hope this helps
Given: <span>y = x^2 + 6x - 5. Then a = 1, b = 6 and c = -5.
The x-coord. of the vertex is given by x = -b / (2a), which here is x = -6 / (2*1) = -3.
Use the given formula </span><span>y = x^2 + 6x - 5 to find the value of y when x = -3:
y = (-3)^2 + 6(-3) - 5 = 9 - 18 - 5 = -14
Then the vertex is (-3, -14).</span>
