Answer:
or 
Step-by-step explanation:
we know that
The surface area of a cube is equal to
where
x is the length side of a cube
In this problem we have
substitute in the formula and solve for x
square root both sides
Answer:
A diagonal
Step-by-step explanation:
So you need to find a number that goes into both of these numbers:
3 goes into both, so divide both by 3
27/3 = 9
42/3 = 14
so your answer is 9/14
Answer:
Step-by-step explanation:
AS we can see the lines are parallel so
2 ( 4x - 3) + 7(x + 3) = 180° ( being so - interior angles)
8x - 6° + 7x + 21° = 180°
15x + 15° = 180°
15x = 180° - 15°
15x = 165°
x = 165° / 15
Therefore x = 11°
Now
2 ( 4x - 3) = 2 ( 4 * 11° - 3°) = 2 ( 44 - 3)° = 2* 41 = 82°
7(x + 3 ) = 7 ( 11° + 3°) = 7 * 14 = 98°
Answer:
y=-10
Step-by-step explanation:
y=-2(3)-4
y=-10
