What is the percent change from 1800 to 1926

Crank

The percentage change is 6.54%
You have to divide 1800÷1926, then multiply by 100 and you'd get 93.46, then subtract 100-93.46 which equals 6.54% :)

4. See if you can find "like-terms" in the expression and

WITCHER [35]

Answer:

After finding like terms and solving, we get $\mathbf{3x^2+3x+16}$

Step-by-step explanation:

We need to find like terms and simplify the expression $4- 2x + x^2 + 5x + 12 + 2x^2$

Like terms: The terms who have same variable and exponent are called like terms.

So, Combining like terms and solving:

$4- 2x + x^2 + 5x + 12 + 2x^2\\=4+12-2x+5x+x^2+2x^2\\Now \ solving:\\=16+3x+3x^2\\Rearranging \ the \ terms:\\=3x^2+3x+16$

So, after finding like terms and solving, we get $\mathbf{3x^2+3x+16}$

<u><em>Note: In the question given we have - and + sign with the term 5x</em></u> i.e 4- 2x + x^2 -+ 5x + 12 + 2x^2

I have solved using +5x, but if the term is -5x then the solution will be:

$4- 2x + x^2 - 5x + 12 + 2x^2\\=4+12-2x-5x+x^2+2x^2\\Now \ solving:\\=16-7x+3x^2\\Rearranging \ the \ terms:\\=3x^2-7x+16$

So, the answer will be: $\mathbf{3x^2-7x+16}$

A triangle has side lengths of (5h – 4k) centimeters, (10h + 7m) centimeters, and

larisa [96]

A mathematical expression which best represents the perimeter of this triangle is (15h - 6k + 12m) centimeters.

<u>Given the following data:</u>

Length A = (5h – 4k) centimeters

Length B = (10h + 7m) centimeters

Length C = (5m – 2k) centimeters.

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

A triangle can be defined as a two-dimensional shape that comprises three (3) sides, three (3) vertices and three (3) angles.

<h3>How to calculate the perimeter of a triangle.</h3>

Mathematically, the perimeter of a triangle is given by this formula:

$P=A+B+C$

<u>Where:</u>

A, B, and C are length of sides.

Substituting the given parameters into the formula, we have;

$P=(5h - 4k) +(10h + 7m) +(5m - 2k)\\\\P=5h+10h-4k-2k+7m+5m\\\\P=(15h-6k+12m)\;centimeters$

Mrs. Plum’s civics class is going on a field trip to observe the state legislature while it's in session. There are 24 students

Scrat [10]

Answer:

2024 ways

Step-by-step explanation:

Because order doesn't matter in this scenario, we can use the binomial function $_nC_k$ , where n is the total number of items (students in this case) and k is the number of items we'd like to choose.

This binomial function is equivalent to:

$_nC_k=\frac{n!}{(n-k)!*k!}$ , where n! means n * (n - 1) * (n - 2) * ... * 2 * 1

Here, we have $_{24}C_3=\frac{24!}{(24-3)!*3!} =\frac{24!}{21!*3!} =2024$ .

Thus, the answer is 2024 ways.
