Which statement explains how you can use a number line to determine the number that is 4 more than –9?
2 answers:
If a number x is something more than another number y, it means that you can obtain x by adding something to y.
So, if we want to get 4 more than -9, it means that we must add 4 to -9: the number you're looking for is
On a number line, bigger numbers lie on the right, so if you start from -9 you should take 4 steps to the right, and you'll land on a number which is 4 more than -9.
Answers.
In a number line system addition mean movement to the right will subtraction is movement to the left which simply implies the bigger numbers lie on the right and the smaller number to the left,
so in the case above starting from -9 you should take 4 steps to the right, and you'll land on a number which is 4 more than -9 which is -5.
-9 + 4 = -5

Answer:
Step-by-step explanation:
To calculate the lenght of the diagonal d across the square, we can assume that the square it is compound of two right triangles. So, we can resolve this exercise using The Pythagorean Theorem.
<em>The Pythagorean theorem</em> states that in every right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the respective lengths of the legs. It is the best-known proposition among those that have their own name in mathematics.
If in a right triangle there are legs of length a and b, and the measure of the hypotenuse is c, then the following relation is fulfilled:
a is the height, b is the base, and c is
the hypotenuse.
To obtain the value of the hypotenuse
To find the value of the lenght of the diagonal d across the square, we have:
Where a = b = 20
Substituting the values
Round the answer to 2 decimal places
