Answer:

Length=19 inches\\\\Width=5 inches

Step-by-step explanation:

Let the width of the rectangle be 'w' inches

length of the rectangle= (2w+9) inches

Perimeter of the rectangle= 48 inches

Perimeter of a rectangle= 2(Length+Width)

                      48=2((2w+9)+w)\\\\48=2(2w+9+w)\\\\48=2(3w+9)\\\\48/2=3w+9\\\\24=3w+9\\\\3w=24-9\\\\3w=15\\\\w=15/3\\\\w=5 inches

                     Width= 5 inches

Length=(2w+9)=2(5)+9=19 inches

Length=19 inches\\\\Width=5 inches

If f(x) = -2[x] + 8, what is f(-1.8)?<br> O 4 <br> O 6<br> O 10<br> O 12
lina2011 [118]

Answer:

12

Step-by-step explanation:

since the function is -2x+8 and you have been told to find f(-1.8) you have to replace -1.8 were there's x in the function.

f(x)=-2x+8

f(-1.8)=-2x+8

=-2(-1.8)+8

=3.6+8

=11.6 round off to 12

I hope this helps
