Hope this helps!
Answer:
i) 56
ii) 90
Step-by-step explanation:
i) 2a (b + c) where a = 2 b = 5 and c = 9
2(2) ((5) + (9))
2(2) (14)
(4) (14)
56
ii) abc
(2)(5)(9)
90
it would be y=3 because if you flip the line of y=-3 over thex-axis, you would get this
Answer:
15. 
16. m<V = 103°
17. 
Step-by-step explanation:
15. The figure given is quadrilateral. Sum of interior angles of a quadrilateral = 360°
Therefore:

Solve for x

Add like terms

Subtract 112 from each side

Divide both sides by 31

16. The polygon is a hexagon. Sum of interior angles of a hexagon = 720. Therefore:

Solve for x

Add like terms

Subtract 321 from each side

Divide both sides by 21

m<V = 5x + 8
Plug in the value of x
m<V = 5(19) + 8 = 95 + 8
m<V = 103
17. The polygon is a regular pentagon. This means each of the angles measures 108°. The sum of the interior angles all together is 540.
Therefore:

Solve for x

Add 18 to both sides

Divide both sides by 9
