Answer:
0.4 of the chocolate bar.
Step-by-step explanation:
<span>The nonpermissible replacement for the variable x in this expression is x = 2
Substituting x = 2 yields:
(2)^2/(2(2)-4)
4/0, which is undefined.

Answer:
(20a+108)/15
Step-by-step explanation:
First find LCM of the denominators. U will find it to be 15
Then calculate the number like this.
[(14a)×1/15×1]+[(2a+36)×3/5]
[(14a/15)]+[(6a+108)/15
(14a+6a+108)/15
(20a+108)/15
1. substitute:
4+(7-5)
2. simplify:
4+2
3. evaluate:
6
the answer is 6.
Answer: The hypotenuse is 53 (approximately)
Step-by-step explanation: In this question we shall apply the Pythagoras theorem which states that;
AC^2 = AB^2 + BC^2
Where AC is the hypotenuse and AB and BC are the two other sides. Having been given that the two other sides are 36 and 39 units respectively, the hypotenuse is now,
AC^2 = 36^2 + 39^2
AC^2 = 1296 + 1521
AC^2 = 2817
Add the square root sign to both sides of the equation
AC = 53.0754
Therefore the hypotenuse is approximately 53 units.
