Answer:
11.25
Step-by-step explanation:
if a cube has 6 equal sides, you want to multiply 5.25 by 6 to get the surface area for the entire cube.
1: 14 ft
2: 18
3: 11; 28
4: 8; 96
5: a = 5x3
6: a = 8x8
7: 1x42, 2x21, 3x14, and 6x7. 6x7 probably makes the most sense.
Step-by-step explanation:
(3×6) + (2×6)
= 18 + 12
= 30 in²
A four sided polygon, 4 edges and 4 corners
Answer:
The answer is below
Step-by-step explanation:
The equation of a straight line is given by:
y = mx + b
where m is the slope of the line and b is the y intercept (value of y when x = 0).
Given the equation of two lines as
, the two lines are parallel to each other if
. Also the lines are perpendicular if

Given line BC:
3x + 2y = 8
2y = -3x + 8
y = -3x/2 + 4
Hence the slope of the line BC = -3/2
For line AD:
-3x - 2y = 6
-2y =3x + 6
y = -3x/2 - 3
Hence the slope of line AD is -3/2
Since both line BC and AD have equal slope (-3/2), hence both lines are parallel to each other
