<h3>Answer: b+5a</h3>

Explanation:

The commutative property of addition is where we can add two numbers in any order.

The general equation is x+y = y+x

A more concrete example would be something like 2+3 = 3+2 since both sides simplify to 5.

For 5a+b, it is the same as b+5a. We swap the two terms.

The first T-shirt you buy costs $7, and every additional shirt costs only $5. Let f(n) be the total cost of n shirts. F is a seq

Zina [86]

Answer:

f(n) = 2 + 5n. This is an arithmetic sequence.

Step-by-step explanation:

f(1) = 7

f(2) = 7 + 5

f(3) = 7 + 5 + 5 = 7 +10

f(4) = 7 + 5 + 5 + 5 = 7 + 15

In general,

f(n) = 7 + 5(n -1 )

= 7 + 5n - 5

= 2 + 5n

We have the sequence 7, 12, 17, 22, 27 …

This is an arithmetic sequence, because it is a sequence of numbers in which the <em>common difference</em> between consecutive terms is 5.

What is the length of side a?

Bad White [126]

$\huge \bf༆ Answer ༄$

According to given figure, The Triangle BDC is a right angled Triangle (Angle D = 90°)

So, we can apply Pythagoras theorem to find the Side a (Hypotenuse)

Now, let's solve ~

$\sf \: BD {}^{2} + CD {}^{2} = BC {}^{2}$

$\sf4 {}^{2} + {3}^{2} = {a}^{2}$

$\sf16 + 9 = {a}^{2}$

$\sf \: a {}^{2} = 25$

$\sf \: a = \sqrt{25}$

$\sf \: a = 5 \: units$

Therefore, Length of side a is 5 units ~
