The rectangle is 7 x 4 so the area is 28 sq cm
The triangle has a base of 4 and a height of 3.
The formula is A = 1/2 * b*h
You have 2 triangles so:
2(1/2)*4*3= 12 sq cm
Add together:
28 + 12= 40 sq cm
To expand you must first distribute (multiply) the 2 to the numbers inside the parentheses
2(x - 5)
(2 * x) + (2 * (-5) )
2x + (-10)
2x - 10
There are no like terms, therefore (x - 5)2 expanded is 2x - 10
Hope this helped!

Answer: 1/4 or 25%
Step-by-step explanation:
The chance of flipping tails is 1/2, so you multiply 1/2*1/2 (for the 2 flips) to get 1/4 (1/2^2=1/4).
Answer:
The domain: All real numbers.
The range: y>0
Step-by-step explanation:
Domain means all possible x values, and by looking at the graph it covers all real numbers.
Range means all possible y values, and since the x axis is a horizontal asyntope, the graph will never touch the x axis, which is why the range is y>0.
