The perimeter of the scalene triangle is 54.6 cm.Which equation can be used to find the value of b if side a measures 8.7 cm?

8.7 + b = 54.6
17.4 + b = 54.6
26.1 + b = 54.6
34.8 + b = 54.6

Answers

Answer 1
Answer: the correct question is
The perimeter of the scalene triangle is 54.6 cm.
Which equation can be used to find the value of b if side a measure 8.7 cm and side c measure 26.1 cm?

we know that
the perimeter of a triangle is equal to

P=a+b+c \n P=54.6 cm equation 1

P=a+b+c \n P=8.7+26.1+b equation 2

equate equation 1 and equation 2
54.6=(8.7+26.1)+b \n 54.6=34.8+b

therefore

the answer is the option D
34.8 + b = 54.6
Answer 2
Answer:

Answer:The correct answer is :

34.8 + b = 54.6

Step-by-step explanation:

The perimeter of the scalene triangle =  Sum of length of all sides

Given that perimeter of the scalene triangle = 54.6 cm

a = 8.7 cm , c = 26.1 cm

a + b + c= 54.6 cm

8.7 cm + b + 26.1 cm= 54.6 cm

34.8 cm+b = 54.6 cm

From the given options the correct answer is:

34.8 cm+b = 54.6 cm

Which of the following represents the factored form of f(x) = x3 − 81x?f(x) = x(x − 9)2
f(x) = (x + 9)(x − 9)
f(x) = x(x + 9)(x − 9)
f(x) = x(x2 − 9)

Answers

Factored form of f(x) = x^(3) -81x is equal to x(x+9)(x -9).

What is factored form?

" Factored form is defined as for the given polynomial product of the constant along with linear expressions."

Formula used

a^(2) -b^(2) =(a+ b)(a- b)

According to the question,

Given polynomial,

f(x) = x^(3) -81x

Simplify the given polynomial to get its factored form using formula,

x^(3) -81x\n\n= x(x^(2) -81)\n\n= x(x^(2) -9^(2) )\n\n= x(x+ 9)(x-9)

Hence, Option(C) is the correct answer.
