Answer:
Final answer is 13.
Step-by-step explanation:
Given expression is
-k+h+kh
We also have been given values of h and k as:
k=-5 h=-2
to simplify the given expression, we just need to plug the given values of k=-5 and h=-2 into -k+h+kh
-k+h+kh
Hence final answer is 13.
X is the unknown value of the variable x. X = 4 means that that value is given to you and the value of x is 4. You are supposed to substitute x in for 4 in that equation.
Answer:
C3H8 + 5O2 → 3CO2 + 4H2O
Step-by-step explanation:
Propane + Dioxygen = Carbon Dioxide + Water
Reaction Type
Combustion
N; n+1; n+2 - three consecutive whole number
n + (n + 1) + (n + 2) = 195
n + n + 1 + n + 2 = 195
3n + 3 = 195 |subtract 3 from both sides
3n = 192 |divide both sides by 3
n = 64
Answer: 64; 65; 66.
One of the rules of triangles is that if you have a 45 45 90 angle triangle, the two sides besides the hypotenuse are equal to each other. In this case, one of the sides is equal to x, so other side is equal to x as well. Now, to solve for x, you need to know the Pythagorean theorum:
Both 'a' and 'b' are equal to x, and 'c' is equal to 3, so I'll make the substitutions below:
This can be simplified to:
Now we just solve for x:
Solution:
