Answer:
132 square units
Step-by-step explanation:
First, I would figure out the areas of the right triangles
Left triangle: 1/2(6x8) =24 units²
Right triangle: 1/2(8x3) = 12 units²
entire rectangle between triangles: 12x8 = 96 units²
add all areas together: 24+12+96 = 132 units²

Answer:
If you actually meant f(x)=2x+3x−1 ,
then note it can be rewritten as:
f(x)=2x−2+5x−1=2+5x−1=y
At this point you can find x in terms of y (“make x the subject”):
y−2=5x−1⟹1y−2=x−15
⟹x=5y−2+1=y+3y−2
Switch variables back to x, and you have the inverse function of f:
g(x)=x+3x−2
How do you know you’ve calculated correctly? The composition of f with g should result in x — that is, evaluate f(g) and you should get the result x:

only option that changes the size
X≈1.5874
