From the graph, we see that the final position of the curve is higher than the original height of the curve, meaning the products have more energy than the reactants.
Hence <em>energy was added for the reactants to become the products</em>. This is why the reaction is endothermic, because the products retained some of the supplied energy.
Part of the energy supplied was used to overcome the activation energy (the peak of the curve). However, this extra energy is recuperated as heat once the product is formed.

→ transitive property of congruence
Answer: (I think it is x=4)
x=4, x=2, or x=10
Step-by-step explanation:
Simplifying
3x + 2(5x) = 26
Remove parenthesis around (5x)
3x + 2 * 5x = 26
Multiply 2 * 5
3x + 10x = 26
Combine like terms: 3x + 10x = 13x
13x = 26
Solving
13x = 26
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '13'.
x = 2
Simplifying
x = 2

Equation at the end of step 1
3 • (x - 2) - (5x - 26) = 0

Pulling out like terms
3.1 Pull out like factors :
20 - 2x = -2 • (x - 10)

Equations which are never true
4.1 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
4.2 Solve : x-10 = 0
Add 10 to both sides of the equation :
x = 10
One solution was found :
x = 10

(3x-3*2)+5x=26
(3x-6)+5x=26
3x-6+5x=26
3x+5x-6=26
8x-6=26
(8x-6)+6=26+6
8x-6+6=32
8x=32
8x/8=32/8
x=2^5/2^3
x=2^5-3
x=2^2
