Use surface area equation 2ab+2bc+2ac plug the numbers in
Answer:
The surface area of the gift box is = 
Step-by-step explanation:
The surface area of the cylinder can be calculated using this formula:

in this case, r is not a number, but rather an expression, which is r =
.
The height of the gift box is twice the radius, which is h = 
To get our curved surface area, we carefully put the expressions for h and r into the equation.




The surface area of the gift box is = 
Answer:
<h2>x = -5</h2><h2>y = -2</h2>
Step-by-step explanation:

y = -4x
y = mx+b
b = 0
m = -4
here are some basic directions:
1. mark the point (0, 0) on the coordinate plane since b, aka the x intercept (where the line intersects with the x axis)
2. mark another point (1, -4) on the coordinate plane since we have defined a hawt slope ykyk
3. use the two points to guide ur ruler and draw a line idk how to describe it but yeah <3
