Write the perimeter of each figure as a trinomial. Must show your work.

noname [10]3 years ago

Answer:

P = 2n + 8m - 1

Step-by-step explanation:

A <u>trinomial is an expression or equation that has three terms</u>. A term is when between the numbers or variables, the operations are neither subtraction nor addition, or when there is only one number.

If two terms have the <u>same variable</u>, called <u>like terms</u>, they can be combined by addition or subtraction.

The perimeter is the total length of all the sides.

The formula for the perimeter of a triangle is P = s_{1} + s_{2}  + s_{3} for each of the three sides.

Substitute each of the three sides.

P = s_{1} + s_{2}  + s_{3}

P = n + (2m + n)  + (6m - 1)

P = n + 2m + n  + 6m - 1 brackets can be removed

P = n + n + 2m + 6m - 1 rearrange equation according to like terms

P = 2n + 8m - 1 collected the like terms by addition

The function h(x) is given below.
zavuch27 [327]

The inverse function will be h⁻¹(x) = {(–5, 3), (–7, 5), (–9, 6), (–12, 10), (–16, 12)}. Then the correct option is B.

<h3>What is inverse of a function?</h3>

Suppose that the given function is

f:X → Y

Then the inverse of the considered function will be

f⁻¹: Y → X

The function h(x) is given below.

h(x) = {(3, –5), (5, –7), (6, –9), (10, –12), (12, –16)}

Then the coordinate of the inverse function gets swapped.

h⁻¹(x) = {(–5, 3), (–7, 5), (–9, 6), (–12, 10), (–16, 12)}

Then the correct option is B.

katrin [286]

Answer: There are 160 different rings.

Step-by-step explanation:

The question is missing, i guess you want to know the number of different rings that the jewelry has:

For the material we have 2 options.

For the stile we have 8 options

For the gem we have 10 options.

Now, the total number of possible combinations is equal to the product of the number of options for each selection, this is:

Combinations = 2*8*10 = 160
