Answer:

the equivalent expression is: 4p^2+8pq-3q^2

Step-by-step explanation:

we are given the expression as: (3p^2+5pq-q^2)+(p^2+3pq-2q^2)

we will firstly combine the terms with same variable term and than apply the corresponding addition or subtraction on its coefficient to get the desired result.

==3p^2+p^2+5pq+3pq-q^2-2q^2\\=(3+1)p^2+(5+3)pq+(-1-2)q^2\\=4p^2+8pq-3q^2

Hence, the desired answer is: 4p^2+8pq-3q^2.

There are 20 students in my class. Each student needs: .2 cups, 2 plates, 1 party hat and a pair of earphones. My teacher has 2
garik1379 [7]

Answer:

Simple, no. This would not be enough.

Step-by-step explanation:

This is because you mentioned that there are 20 students and each of them needed 2 plates. So, there would need to be at least 40 plates. Forks seem irrelevant in this question but if the teacher has 8 plates in 1 box and another 8 in the second box, that would sum up to 16 plates that are available. And the fact that the box doesn't even include the other items, should hint the lack of items available for the students.

This question seemed worded differently. But tried my best. :)

The area of square LMNP is 50

<h3>What is a circle?</h3>

A circle is the locus of points equidistant from a fixed point which is known as the center of the circle.

A circle is defined if the center and the radius is known.

Analysis:

Perimeter of a circle = 2πr

Given perimeter = 10π

2πr = 10π

2r = 10

r = 10/2 = 5

r = MO

so the diagonal of the square is actually the diameter of the circle = 5+5 = 10

To find the side, x of the square the diagonal and the sides form a right-angled triangle, by  Pythagoras, 10^{2} = x^{2} + x^{2}

2x^{2} = 100

x^{2} = 100/2 = 50

Also area of square is x^{2} = 50

In conclusion, the area of square LMNP is 50
