Answer:70
Step-by-step explanation:
K = 6x + 100
K=6 • -5 + 100
= -30 + 100
= 70
Answer:
7f - 3
Step-by-step explanation:
We'll combine like terms to simplify this. Adding anything with an f (the variable) to anything else with an f, and adding just plain numbers to just plain numbers.
2f + 5 + 5f - 8
= 2f + 5f + 5 - 8
= 7f - 3
Answer:
8√3
Step-by-step explanation:
Pythagorean theorem.
8^2+x^2=16^2.
This is also a 30-60-90 triangle.
That means x=8√3 if you follow rules of 30-60-90 triangle or solve using pythagorean theorem.
First, we already have the perimeter and the sides that we need to find the 5th sides. Next, add all available sides that we have: 5+5+4+4=18. Finally, we need to subtract 27 to 18 to get the final answer is 9 for the 5 the side. Hope you get it.
