Answer:

The inequality (10)< s < (60) represents the possible third side length of the triangle, s, in centimeters.

The inequality (70)< p < (120)represents the possible values for the perimeter, p, of the triangle, in centimeters.

Step-by-step explanation:

Consider the provided information.

The sum of any 2 sides of a triangle must be greater than the measure of the third side.

Let say the third side 's' is the smallest side, then according to above condition.

25+s>35\\s>35-25\\s>10

Let say the third side 's' is the largest side, then according to above condition.

25+35>s\\60>s

Hence, the combined inequality is: 10

Perimeter of a triangle is the sum of the length of all sides.

p=25+35+s\\p=60+s

If s>10 then the perimeter will be:

p>60+10

p>70

If 60 then the perimeter will be:

p

p

Therefore, the combined inequality is: 70

we know that

The <u>Triangle Inequality Theorem</u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

so

Let

s------> the length of the third side

25+s > 35 \\ s > 35-25 \\ s> 10\ cm          

25+35 > s \\ 60 > s \\ s< 60\ cm  

10\ cm < s < 60\ cm

therefore

<u>The answer part a) is</u>

10\ cm < s < 60\ cm

we know that

the perimeter of a triangle is the sum of the length sides

In this problem

P=25+35+s\\P=60+s

<u>For s> 10\ cm</u>

the perimeter is equal to

P > 60+10\\ P>70\ cm

<u>For s< 60\ cm</u>

the perimeter is equal to

P < 60+60\\ P

so

70\ cm < P < 120\ cm

therefore

<u>the answer part b) is</u>

70\ cm < P < 120\ cm

Let f(x) = x2 − 8x + 5. Find f(−1).
Westkost [7]
F(x) = x^2 - 8x + 5

f(-1) = -1^2 - 8(-1) + 5
f(-1) = 1 + 8 + 5

How to make 4.5 into a fraction
Zepler [3.9K]
The fraction is 4 1/2. Just convert the decimal into a fraction. 50/100 is the same as 5/10 which is the same as 1/2.

Explain the differences between properties of equality and properties of inequality when solving equations and inequalities.
matrenka [14]
Equalities will have the words "is" or "equals" or "the same as" in the wording. These produce a unique solution.

Inequalities have phrases like "at most" or "at least" or "no more than" in them. Solutions are a range of values, ranging between 2 values, or from a particular value to positive or negative infinity.
