Hi there! The answer is x = 6

Since the length of both sides is the same, we get the following equation:
5x + 10 = 40

Subtract 10 from both sides
5x = 30

Divide both sides by 5.
x = 30 \div 5 = 6

The two sides are congruent (because of the straight line through the side)

set them equal to one another

5x + 10 = 40

Isolate the x, do the opposite of PEMDAS

5x + 10 = 40

subtract 10 from both sides

5x + 10 (-10) = 40 (-10)

5x = 30

divide 5 from both sides

5x/5 = 30/5

x = 30/5

x = 6

6 is your answer for x

hope this helps

How many moles of methane are produced when 4.53 mol co2 reacts
ArbitrLikvidat [17]
The reaction formula CH4 + 2O2 → CO2 + 2H2O shows the oxidation of 1 mole of CH4 (Methane) will yield 1 mole of CO2 (Carbon Dioxide). Since 1 mole of CH4 will weigh 12g (for the Carbon) + 4g (1g for each Hydrogen) = 16g, then 32g of CH4 will correspond to 32g / 16g/mole = 2 moles. Therefore the oxidation of 2 moles of CH4 will yield 2 moles of CO2.
