When would we need to calculate circumference of a circle? Area of a circle?
Alex_Xolod [135]
If you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14. You can also work out the circumference of a circle if you know its radius.

Product of polynomials can be done by using distributive property of multiplication over addition. The needed product is: Option

<h3>What is distributive property of multiplication over addition?</h3>

Suppose a, b and c are three numbers. Then we have:

a(b + c) = a\times b + a\times c

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

<h3>What are like terms?</h3>

Those terms which have same variables raised with same powers.

For example, 5x^3 and x^3 are like terms since variable is same, and it is raised to same power 3.

For example x^3 and 4x^4 are not like terms as the variables are same but powers aren't same.

For the given case, the expression is 2x^4(3x^2 +4x +1)

Using the distributive property of multiplication over addition, we get the product result as:

2x^4(3x^2 +4x +1) = 6x^{4+2} + 8x^{4+1} + 2x^4 = 6x^6 + 8x^5 + 2x^4

(when like terms are multiplied, powers are added of the variables (same variable) due to property  a^b \times a^c = a^{b+c} )

Jessica, Hans, and Tom sent a total of 95 text messages during the weekend. Tom sent 3 times as many messages as Hans. Jessica s
Virty [35]

Answer: Manal = 27 messages

Elisa = 17 messages

Abdulrahman = 51 messages

Step-by-step explanation:

Let tye number of messages that Manal sent be x.

Since Eissa sent 10 fewer messages than Manal, this will be:

= x - 10

Abdulrahman sent 3 times as many messages as Eissa. This will be:

= 3(x - 10) = 3x - 30

We are also told that Manal, Abdulrahman, and Eissa sent a total of 95 text messages. This will be:

x + (x - 10) + (3x - 30) = 95

x + x - 10 + 3x - 30 = 95

x + x + 3x - 10 - 30 = 95

5x - 40 = 95

5x = 95 + 40

5x = 135

x = 135/5

x = 27

Manal = x = 27

Elisa = x - 10 = 27 - 10 = 17

Abdulrahman = 3x - 30 = 3×27 - 30 = 81 - 30 = 51

Manal = 27 messages

Elisa = 17 messages

Abdulrahman = 51 messages
