Answer:
96 ft^2.
Step-by-step explanation:
Area of shaded region = area of the original rectangle - area of the one removed
= 8 * 16 - 8*4
= 128 - 32
= 96
Answer=4
8*16=128
your number is 8
therefore half your number is 4
8/2=4
Answer:
O No
Explanation:
Given equation: y = 13x + 12
To check if (2, 8) is a solution of the given equation.
Substitute x and y value in equation and check if it is true.
(x, y) = (2, 8)
simplify
This following statement is false and hence (2, 8) is not a solution.
Tanx sinx (cos^2x cscx- sinx)
=(sinx/cosx)((cos^2x cscx- sinx)
=(sinx/cosx)((cos^2x 1/sinx- sinx)
=(sinx/cosx)((cos^²x - sin²x)] / sinx
=(sinx/cosx)((cos^²x - sin²x)] / sinx
=(1/cosx)((cos^²x - sin²x)]
=(1/cosx)(2cos²x====> = 2 cos x]
