2+2=4 because if you have 2 and you add another 2 you will have 4
Answer:
yes
Step-by-step explanation:
A relation is a function in which for each input there is only one output.
In a relation, y is a function of x.
Now we look at the mapping
For input 6, -1 is the output
for input -1, 2 is the output
for input 4, 3 is the output
for input 0, 3 is the output
For each input , there is an output. Input is not repeating. Input is occurring only once.
So this relation is a function.
Answer:
Natural Numbers, Whole Numbers, and Integers are rational numbers.
Example: {1, 2, 3, -1, -2, -3}
Numbers with repeating decimals and terminating decimals are also rational.
Example: {2.34343434..., 3.45}
If a square root makes a perfect square, then it is rational.
Example: {√16, √100}

Surface area = area of 3 rectangles + 2 triangles
= 3*(3*7) + 2 * ( 1/2 * 3 * 2.6)
= 63 + 2* 3.9
= 70.8 in^2
