Answer: 349 square units
============================================
Work Shown:
- L = 5.5 = length
- W = 5 = width
- H = 14 = height
SA = surface area of rectangular prism
SA = 2*(L*W + L*H + W*H)
SA = 2*(5.5*5 + 5.5*14 + 5*14)
SA = 2*(27.5 + 77 + 70)
SA = 2*(174.5)
SA = 349
The surface area is 349 square units.
Answer:
60km
Step-by-step explanation:
There are two ways to look at this
1. Finding the unit rate
We can find how many km he travels in 1 hour by diving both the hours and km by 2. 1 hour = 10km so 6 hours is 60km since we multiply by 6.
2. Multiply by 3
We can multiply both the km and hours by 3, since 2x3=6 hours
20km * 3 hours = 60km
Answer: the smaller number is 8. The larger number is 38
Step-by-step explanation:
Let x represent the smaller number.
The The larger of the two numbers is eight more than three times the smaller number. It means that the larger number is 3x + 8
The sum of the two numbers is 48. It means that
x + 3x + 8 = 48
4x + 8 = 48
4x = 48 - 8 = 40
x = 40/4 = 10
Substituting x = 10 into 3x + 8, it becomes
3 × 10 + 8 = 38
Answer: 6x
Step-by-step explanation:
we shall go right to left in the function
g(3x)
2(3x)
6x
Answer:
the answer is x = 4 + √13 or x = 4 − √13
