Answer:
y = - 
Step-by-step explanation:
= 
( cross- multiply )
4y = - 7 ( divide both sides by 4 )
y = -
The intervals along the x axis are inconsistent. the one that says 21-30 should either be split into 2 or have twice the width.
Hope this helps :)
Answer:
-6
Step-by-step explanation:
15/4 ÷ -5/8
Copy dot flip
15/4 * -8/5
Rewrite
15/5 * -8/4
3 * -2
-6
Answer:
Below in bold.
Step-by-step explanation:
This is a regular polygon so all sides are congruent, therefore:
The perimeter of the polygon = 6*34 = 204 units.
We can divide the polygon into 6 conguent triangle with height 30 and base 34.
So area of 1 triangle = 1/2*34*30 = 510.
So area of the polygon = 6 * 510 = 3060 unit^2.
Perimeter of the polygon = 6*34 = 204 units.
