You have 3hours 25seconds left to assemble the machine.
So you do 18 x 8 to get the area of the rectangle bit. (18 x 8 = 144)
Then you can put the two half circles together to make a full circle. Area of a circle is
pi x radius x radius
so the radius would be half of the diameter (8/2 = 4)
so area would be:
Pi(equal to around 3.14) x 4 x 4 = 50.2
then you add the areas of the rectangle and circle
144 + 50.2 = 194.2
Answer:
7x^2 + 14x - 12
Step-by-step explanation:
Add like terms:
(4x + 8x - 5) + (3x2 + 6x - 7) becomes:
4x^2 + 8x - 5 or (grouping like terms in columns):
+ 3x^2 + 6x - 7
---------------------
7x^2 + 14x - 12
