Answer:
40 units
Step-by-step explanation:
i took the test
(I)
we are given when we add numbers of same sign
For exp: +2+3=+5
-2-3=-5
We can see that we are adding numbers and then we put same sign in front
so, we can fill spaces
When adding integers with the same sign, you add the numbers and put the sign
(II)
we are given when we add numbers of different signs
For exp: 2-3=-1
-2+3=+1
We can see that we are subtracting numbers and then we put sign of largest value in front
so, we can fill spaces
When adding integers with different signs you subtract the numbers and use the sign of the largest absolute value
From the options presented, only figure number 2 or the one that looks like a cross has a rotation symmetry.
<h3>What is rotation symetry?</h3>
This type of symmetry implies that when a figure is rotated it matches its original shape. An example of this is the circle.
<h3>Which figures have rotation symmetry?</h3>
From the options presented, only the cross has this symetry because its side are equal and this means you can rotate it and it will look the same.
