Answer:24cm
Step-by-step explanation:
if there is 2 sides with the same like the length is 8 and 2 sides(8*2)=16
and the width is half (8/2) =4 double for 2 sides (4*2) = 8
8+16
51 I thinks that’s the correct answer
Oi
Just calculating the differential. Step by step:
If you want to know where the tangent has no slope:
A Domain is the lowest and highest x value (-5,-2) is how it is formatted this means -5 to -2
Range is the lowest to highest Y value so (-3,3)
(-5,-2) - domain
(-3,3) - range
B Intercept are when the line crosses the acis labeled x so
(-2,0) and (2,0)
C F(1) means what is x when y is equal to 1 so we must estimate this
(-1,1) and (1.5,1)
D f(x) = -3 is when y is -3 so we look at the graph to see
-5 and 4 are the values for x
E f(x) < 0 means when y is above the x axis
This is between the x values of -2 and 2 or (-2,2)
