Answer:
2
Step-by-step explanation:
(8-x)(8+x)
8×8=64
-x·+x=-x^2
64-x^2
Answer:
1240.4 mm²
Step-by-step explanation:
SA of Pentagonal pyramid:
(as)(5/2) + (sl)(5/2)
↑ ↑
base area lateral area
_____________________
a: apothem (in-radius) length, s: side length.
l: slant height.
______________________
Since we are already given the base area which is 440.4 mm². All we need to do is find the lateral area and add both areas together.
Given that the triangular face of the lateral part has a side/base length of 16mm, and a 20mm slant height.
A triangle has an area of ½bh and since there are 5 of these faces total, (5)(½bh) = (5/2)(bh). In a three dimensional perspective, b will be s and h will be l so (sl)(5/2).
With this information the surface area is:
(16)(20)(5/2)mm + (440.4 mm²) →
800 mm² + 440.4 mm² =
1240.4 mm²
Answer:
2x + 7 + 3 - 2
Step-by-step explanation:
standard form
Given:
A car dealer acquires a used car for $14,000, with terms FOB shipping point.
Transportation cost = $100
Shipping insurance = $120
Car import duties = $970
To find:
The total inventory costs assigned to the used car.
Solution:
We know that,
Inventory costs = Value of used car + Transportation cost + Shipping insurance + Car import duties
Inventory costs = $14,000 + $100 + $120 + $970
Inventory costs = $15,190
Therefore, total inventory costs assigned to the used car is $15,190.
Answer: x = 5
Step-by-step explanation:
1. Set the two given expressions equal to each other (because the problem says they are interchangeable)
-5x = -40+3x
2. Subtract 3x from -5x to have x on one side of the equation.
-8x = -40
3. Divide each side by -8 to get the value of x.
x = 5
