Answer:

Jenny is wrong the correct answer is x²+ 4 - 4 x.

Step-by-step explanation:

Given that

(x-2)³∕x-2

(x-2)³∕(x-2) =(x-2) (x-2)²∕(x-2)

(x-2)³∕(x-2) = (x-2)²

As we know that

(a-b)² = a²+b² - 2 ab

So

(x-2)² = x²+ 2² - 2 ˣ 2 ˣ x =  x²+ 4 - 4 x

(x-2)² =  x²+ 4 - 4 x

It means that

(x-2)³∕(x-2) = (x-2)² =  x²+ 4 - 4 x

So Jenny is wrong the correct answer is x²+ 4 - 4 x.

16.437 rounded to the nearest tenth
vfiekz [6]
16.4 is the answer. How to get the answer and others like it is like this. The first number after the decimal is the tenth place signaled by this .1 (For the examples I will always put the "1" where the value I'm trying to show) the hundredth place is here .21, and the thousandth is here .321 , hope this helps.

Jamal hiked on two trails. The first trail was 5 1/3 miles long and the second trail was 1 3/4 times as long as the first trail.
earnstyle [38]

Answer:

Jamal hiked = 44/3 miles

Step-by-step explanation:

Mixed numbers are given in this question which can be changed into fractions by multiplying the denominator by quotient and adding numerator to it.

Given that:

Length of first trail: 5 1/3 = (3*5 + 1)/3 = 16/3 miles

According to given condition:

Length of second trail: 1 3/4 * 16/3 = (4*1+3)/4 * 16/3 = 7/4*16/3

By simplifying:

Length of second trail = 28/3 miles

So the total miles Jamal hiked = 16/3 + 28/3

Jamal hiked = 44/3 miles

i hope it will help you!

Find the circumference of the circle. Round to the nearest tenth.
Natasha_Volkova [10]

Formula for the circumference of a circle: C = pi x diameter

We are given the radius here, but we need the diameter. The diameter of a circle is equal to two times the radius.

diameter = 40 x 2 = 80 in

C = pi x 80

C = 80pi = 251.3 in

Hope this helps!! :)
