Answer:
7 feet
Step-by-step explanation:
Assuming that the piece of painting is in the shape of a rectangle.
It is given that the width is 4 feet long and that the area is 28 feet².
We know that the Area of a rectangle is given by the formula length x width.
To find the length, we divide the area by the width.
Length = 28 ÷ 4 = 7 ft
So the length of the painting is 7 feet long.
I think the total area of both is 3,864
so you want to get x to one side only.
3.4x-5=2.4x
add 5 to both sides
3.4x=2.4x+5
now get x to one side by subtracting 2.4x
so x=5
Oh how fun, functions!! You substitute f(-2) into your starting function so it will look like this:
f(x)=2(5x+7)
f(x)=10x+14
f(-2)=10(-2)+14
f(-2)=(-20)+14
f(-2)=(-6)
divide by negative 2 on each side to find f:
f=3
