The given expression is a result of squaring binomials

<h3>Factoring quadratics </h3>

From the question, we are to determine whether the given expression is a result of multiplying conjugates together, squaring binomials, or neither

The given expression is

9z² +54z +81

To do this,

First, we will factor the expression

Factoring the expression

9z² + 54z + 81

First, factor out 9

9(z² +6z +9)

9(z² + 3z + 3z + 9)

9[z(z + 3) + 3(z + 3)]

9[(z +3)(z +3)]

9[(z +3)²]

This can further be expressed as

3²[(z +3)²]

[3(z +3)]²

(3z +9)²

Hence, the expression is a result of squaring binomials

Do<br><br> 5cm<br> 5cm<br> 15 cm<br><br> form a triangle?
Ivahew [28]

Answer:

No

Step-by-step explanation:

No, 5cm, 5cm, and 15cm cannot create a triangle because the side lengths do not follow the formula a + b > c. Since 5 + 5 = 10, and 10 is not greater than 15, these side lengths won't be able to form a triangle.

Hope this helps!!

 Sandra sells necklaces at a school craft fair. She uses the equation P= 7.5n - (2.25n + 15) to determine her total profit at th
gregori [183]
The way you find profit is to subtract the revenue and the cost
Profit = Revenue - Cost
The revenue is the amount of money coming in, the cost is the amount of money going out. The goal of course is to have the revenue larger than the cost so that the profit is positive. 

So the equation given is
P = 7.5n - (2.25n+15)
and its in the form
P = R - C
where...
R = 7.5n is the revenue equation
C = 2.25n+15 is the cost equation

Focus on the revenue equation
R = 7.5n
which is the same as 
R = 7.50*n

This tells us that Sandra pulls in a total of 7.50*n dollars where n is some positive whole number. It represents the number of necklaces sold. For example, if she sold n = 10 necklaces, then
R = 7.50*n
R = 7.50*10
R = 750
meaning that Sandra has made $750 in revenue

As you can see above, the revenue is computed by multiplying the price per necklace ($7.50) by the number of necklaces sold (n) to get R = 7.50*n

So that's why the answer is $7.50

Note: The 2.25 is part of the cost equation. This is known as the variable cost. It is the cost to make one necklace ignoring the fixed cost (eg: rent). The variable cost often doesn't stay the same, but algebra textbooks often simplify this aspect.

a) value of x:

ZX =(10x+9)°

122°=( 10x+9)

122 - 9= 10x

113= 10x

x = 113/10= 11.3 °

so answer is = 11.3°

b) measure of Arc XZ :

formula to find Arc= © angle÷360 x 2πr

A = 122÷360 x 2πr

A = 61/180x 2πr

A = 0.3388x2πr

A= 0.6776πr
