Simplify (3n – 2m)2 = ? a. 6n2 – 12mn – 4m2 b. 9n2 – 12mn – 4m2 c. 9n2 12mn 4m2 d. 9n2 – 12mn 4m2

Answers

Answer 1

Answer: If you would like to simplify (3n - 2m)^2, you can do this using the following steps:

(3n - 2m)^2 = 3^2 * n^2 - 3 * 2 * 2 * n * m + 2^2 * m^2 = 9n^2 - 12nm + 4m^2

The correct result would be d. 9n^2 - 12nm + 4m^2.

Graph the line with slope 1/3

passing through the point (-2, 5).

Answers

Answer:

y = 1/3x + 17/3

Step-by-step explanation:

Required answer: Below

Detailed explanation:

Let's find the equation of the line first.

We know that the line:

has a slope of 1/3
passes through (-2,5)

So, we use these pieces of information and plug them into the formula:

$\bf{y-y_1=m(x-x_1)}$

$\bf{y-5=(1)/(3)(x-(-2)}$

$\bf{y-5=(1)/(3)(x+2)}$

Now let's graph it.

Consider the following sequence: 87; 84; 81... Find an expression for term n of the sequence

Answers

Answer:

$a_(n)$ = 90 - 3n

Step-by-step explanation:

There is a common difference between consecutive terms, that is

84 - 87 = 81 - 84 = - 3

This indicates the sequence is arithmetic with nth term

$a_(n)$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 87 and d = - 3 , then

$a_(n)$ = 87 - 3(n - 1) = 87 - 3n + 3 = 90 - 3n

The number of eggs in 3.25 dozen will be 39.

What is multiplication?

Multiplication is the process of determining the product of two or more numbers in mathematics. A product, or an expression that specifies factors to be multiplied, is what happens when you multiply two numbers in mathematics.

Given that there are 3.25 dozens of eggs. The number of the eggs will be calculated as below:-

There are 12 numbers in a dozen. To calculate the number of eggs multiply the numbers 3.25 and 12.

Number of eggs = 3.25 x 12

Number of eggs = 39

Therefore, the number of eggs in 3.25 dozen will be 39.

Hi,

One dozen of eggs = 12 eggs.

$3.25\cdot 12 =(3+0.25)\cdot 12=3\cdot 12 +0.25\cdot12=36+\frac{12}4=36+3=39\;eggs.$
