Which two numbers selected from the list do not support the following statement?
"the product of an irrational number and an irrational number is irrational."
a) π and π
b) -√7 and π
c) π and √7
d) √7 and 1 over √7
i really need with this, it is really hard to understand. i need answers quickly.

√7 and 1 over √7

Step-by-step explanation:

we know that

A rational number is a number that can be expressed as a fraction where both the numerator and the denominator in the fraction are integers.Numbers that are not rational are called irrational numbers

Verify each case

case A) π and π

The product is a irrational number

case B) -√7 and π

The product is a irrational number

case C) π and √7

The product is a irrational number

case D) √7 and 1 over √7

The product is a rational number

Because

therefore

The numbers do NOT support the statement "The product of an irrational number and an irrational number is irrational."

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.

answer: it is d
