Answer:
1) 33 cm squared
2) 212.5 cm squared.
Step-by-step explanation:
1) Split the figure into a rectangle and a square. The rectangle is 8 (4 times 2) and the square is 25 (5 times 5). 25+8 =33.
2) Find the area of the shaded and unshaded. 14 times 25 equals 350. Then find the area of the unshaded triangle. 11 times 25 divided by 2 is 137.5. Now subtract. 350-137.5 = 212.5.

Answer:
The equation of the line is: y=2x + 3
Mutiply them all out, you'll get quadratic equations. Replace x's with numbers and then you'll be able to draw the graphs
2x + x + 10 + x = 110
4x + 10 = 110 (Subtract ten from both sides)
4x = 100 (divide both sides by four)
x = 25
Plug in values to check...
2(25) + 25 + 25 + 10 = 110
50 + 50 + 10 = 110
110 = 110
