Answer: the perimeter is 40.9 ft
Step-by-step explanation:
The given figure is a trapezium. It is made up of a rectangle and a right angle triangle.
The perimeter of the trapezium is the distance around the figure. This means that the inner dimensions are not included.
Since the opposite sides of the rectangle are equal, it means that the base of the trapezium would be
10 + 4 = 14 ft
Therefore, the perimeter of the trapezium would be
8 + 10 + 8.9 + 14 = 40.9 ft
I think it is self explanatory. Good luck! And remember you can always use long division if you don’t prefer synthetic division. Just rewrite the coefficients in the proper equation. :)
Step-by-step explanation:
3(x+3) - 2(x+2) =
3x + 9 - 2x - 4 =
x + 5
always remember the rules when combining signs and operations (therefore it is -4 at the end after doing the multiplications) :
++ = +
+- = -
-+ = -
-- = +
Answer:
Step-by-step explanation:
sinD = opposite/hypotenuse = 12/15 = 4/5
cosD = adjacent/ hypotenuse = 9/15 = 3/5
sinE = opposite/hypotenuse = 9/15 = 3/5
cosE = adjacent/ hypotenuse = 12/15 = 4/5
The answer is two an a half litres
