Answer:
A C and E
Step-by-step explanation:
If the sides were 2 and 3 then using Pythagoras the diagonal would be sr(2^2 + 3^2) = sr(13)
The actual diagonal is 8 inches so the sides need to be scaled by 8/sr(13)
The screen area will be 2 x 8/sr(13) x 3 x 8/sr(13) = 29.539....
Rounded to nearest sq.inch this is 30 sq.inch
Answer:
24
Step-by-step explanation:
To find f(#) or g(#), plug the number into each x of the equation.
f(x) = -x + 5
f(2) = -(2) + 5
Simplify the parentheses by multiplying.
f(2) = -2 + 5
Add.
f(2) = 3
g(x) = 3x + 2
g(2) = 3(2) + 2
Simplify the parentheses by multiplying.
g(2) = 6 + 2
Add.
g(2) = 8
Now they are asking you to multiply
f(2) • g(2)
3 • 8
= 24
Hope this helps!
