What is the value of x in the equation 13x - 2(8 + 5x) =12 - 11x
2 answers:
Answer: x = 2
Step-by-step explanation:
The given equation :
T o solve the above equation for x , we use BODMAS ( Bracket → Of → Divide→ Multiply→ Add→ Subtract)
According to BODMAS , we first simplify brackets , we get
[∵ (-)(+)=(-)]
Add 11x and 16 on both sides and combine like terms,
Divide both sides by 14 , we get
Hence, the value of x = 2

Answer:
The length of the third side of the triangle is 30.
Step-by-step explanation:
Here is the formula for the Pythagorean Theorem:
The hypotenuse, based on the problem, is 50. Anyways, let's get back to calculating!
We need to multiply 40 times 40 and 50 times 50.
40 times 40, or 40 squared, equals to 1600.
50 times 50, or 50 squared, equals to 2500.
Now, let's subtract. 2500 - 1600 = 900. We need to find the square root of 900--which is 30, because 30 times 30, or 30 squared, equals to 900.
