Answer:
A 6 cm²
Step-by-step explanation:
The formula for the Surface Area of a Rectangle Prism and Square Prism [Cube] is below:
S.A = 2hw + 2bw + 2hb
Since 1 is the length of all edges, and also because all edges are congruent on a cube, you plug in 1 for the <em>height</em>, <em>width</em><em>,</em><em> </em>and<em> </em><em>base</em>:
6 = 2[1][1] + 2[1][1] + 2[1][1]
2 2 2
Or, you can just simply plug in 1 into the formula the exercise gave you and be done with it.

Answer:
y=2x+6 ; x+y=51
Step-by-step explanation:
assuming x is one number and y is the other -
one number (y) is 6 more (+6) than twice another (2x) -
using that knowledge we form an equation -
y=2x+6
the sum (x+y) is 51
using this knowledge we can make the equation -
x+y=51
now you have -
y=2x+6 or 2x-y=-6
x+y=51
using system of equations -
you add the equations -
3x=45
x=15
y=51-x => y=36
hope this helps!!
(86.8 - 3n)/4
You can get this by combining the two. Make sure to give common denominators.
