Choose all expressions that when added result in a rational number 3/5 plus 3/7 0.125 plus 5 1/2 plus 0.375 \sqrt2 plus 4 \sqrt4 plus 2/5 1 plus \pi my bro

plus

0.125 plus 5

plus 0.375

√4 plus  

Step-by-step explanation:

A rational number is a real number that can be expressed in the form of

Where, p and q are integers,

Such that, q ≠ 0

Also, a terminating decimal and root of a perfect square number are always rational numbers,

∵ When we add two rational numbers then the resultant number is always a rational number,

Since, and are rational number,

must be a rational number,

Similarly,

(0.125 + 5), (√4 + )  and (1/2 + 0.375) are rational numbers,

While, if a real number is not a rational number then it is irrational,

Now, the sum of rational number and irrational number is always an irrational number,

⇒ (√2 + 4) and (1+ ) are irrational numbers.

can i get the link to the assignment?

step-by-step explanation:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
