I just divided 9 by 20 and 1 by 4 then subtract 0.45-0.25 = 0.2
Answer:
y=3x-1 and y=3x+1
Step-by-step explanation:
y=mx+b form
m stands for the slope which is rise over run.
b stands for the y intercept. where the line intersects with the y axis.
Yes, they r different lines, bcoz one is 2*x, and another is -2*x. so they r vertical.
Answer:
The surface area of the prism is 48 units².
Step-by-step explanation:
Remember, a net is simply the outer surface of a 3D shape flattened and spread out as a combination of 2D shapes.
With this info, the rest is relatively easy.
The net shows that there are 4 rectangular sides and 2 square sides. We also know the lengths and widths of all of them.
One rectangle is 5 units long and 2 units wide. One square is 2 units long and 2 units wide.
Let's put this into an equation.
4( 5*2 ) + 2( 2*2)
We are adding the areas of the rectangles and squares.
So, let's simplify that equation.
4(10) + 2(4)
40 + 8
48
