2 answers:
Answer:
The correct option is 1.
Step-by-step explanation:
The given expression is
To solve these type of expressions we have a rule that is known as BODMAS.
BODMAS = brackets of division, multiplication, addition, subtraction.
It defined the order of calculations. It means first we have solve the brackets, then division, then multiplication, after that addition and last subtraction.
So according to BODMAS, Claudio should simplify the bracket first.
The bracket of given expression is (7.1+0.5).
The simplification of given expression is shown below.
(Brakets)
(Multiplication)
(Addition)
Therefore he will solve (7.1+0.5) first. So, option 1 is correct.

For the triangle, x is 12 units long.
Step-by-step explanation:
Step 1:
According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
The hypotenuse is the side which is the longest in the triangle and is always opposite the right angle.
In the given triangle, the hypotenuse is 13 units long. The other two sides measure 5 units and x units.
Step 2:
By substituting the known values, we get
Rounding this off to the nearest hundred, we get that x is 12 units long.
