Answer: 37.5
Explanation: find the surface area of one side, which is 2.5*2.5=6.25 then multiply that product by six, since there’s six sides in a square, and you’ll get 37.5
Answer:
-3
Step-by-step explanation:
Slope of a line is "rise over run". Pick two points on the line. For example, (0,4) and (1,1). As we move from the first point to the second, we move down 3 units and right 1 unit. So the slope is -3/1 = -3.
Here's an algebraic approach. If the two points are (x₁, y₁) and (x₂, y₂), then the slope is:
m = (y₂ − y₁) / (x₂ − x₁)
Plugging in our two points:
m = (1 − 4) / (1 − 0)
m = -3
Answer:
18 units
Step-by-step explanation:
If you draw lines from the corner points (L, E, J, and P) to the center, you will find that they bisect the corner angles. For the lines to be tangent, LU=LK, PU=PV, JV=JS, and ES=EK.
Perimeter=LK+KE+ES+SJ+JV+VP+PU+UL
Since LU=LK=4, PU=PV=1, JV=JS=2, and ES=EK=2
Perimeter=4+2+2+2+2+1+1+4
Perimeter=18
Answer:
X = -5/2

Answer:
(2x - 7)³ ≠ (2x)³- 7³
Step-by-step explanation:
(2x - 7)³= (2x)³- 7³
Use pascal's triangle to expand left side. Simplify all else.
(2x)³ + 3(2x)²(-7)¹ + 3(2x)¹(-7)² + (-7)³ = 8x³- 343
8x³ + 3(4x²)(-7) + 3(2x)(49) + (-7)³ = 8x³- 343
8x³ - 84x² + 294x - 343 = 8x³- 343
LS ≠ RS
