Answer:
w = 10
Step-by-step explanation:
This 2-step linear equation is solved by subtracting the constant on the left (8.25), then multiplying by the inverse of the coefficient of w.
8.25 +1/4w = 10.75
1/4w = 2.50 . . . . . . . . . subtract 8.25
w = 10 . . . . . . . . . . . . . .multiply by 4
Answer: The area is 268 cm squared (approximately)
Step-by-step explanation: The area of a parallelogram is given as ;
Area = b x h
Where b is the base and h is the vertical height. However the vertical height is not given, so we shall apply the trigonometric ratio to determine the vertical height. If we draw a straight line from the the top right vertex down to the base, we would have constructed a right angled triangle with hypotenuse 13cm, and reference angle 79 degrees. We can now calculate the vertical height as follows;
Sin 79 = opposite/hypotenuse
Sin 79 = h/13
By cross multiplication we now have
Sin 79 x 13 = h
0.9816 x 13 = h
12.76 = h
With the vertical height now known, we can calculate the area as follows
Area = b x h
Area = 21 x 12.76
Area = 267.96 cm squared
well logically i dont think you could simplify this problem since both of your variables arent like terms... you couldnt add them because of the squared 2c. im sorry i couldnt help you
