Find the length of FE
Please explain it, I'm a little lost.
The centroid (the point where the medians meet) divide each median into parts with lengths in a ratio of 2:1. This means 7x + 1 is twice the length of 3x + 4, or
7x + 1 = 2 (3x + 4)
Solve for x :
7x + 1 = 6x + 8
7x - 6x = 8 - 1
x = 7
Then XE has length
XE = 4•7 - 2 = 28 - 2 = 26
FX is twice this length, so
FX = 2•26 = 52
and so FE has length
FE = FX + XE = 52 + 26 = 78

Step-by-step explanation:
A polynomial is an expression which has many terms. Each term is separated by addition or subtraction. The standard form of a polynomial is and is written in descending order by exponent. The highest exponent is known as the degree of the polynomial. The leading term at the beginning has a leading coefficient.

determine the value of x , (5)(x)=0
Answer:
x=0
Step-by-step explanation:
The parenthesis mean that it's multiplication, so it might be easier to convert that to: 5 · x = 0. We then know that anything times zero equals zero, so 5 · 0 = 0! I hope this helps! :)

Step-by-step explanation:
Step 1: Define
6 + 18r = 20r - 18 - 4r
Step 2: Solve for r
Combine like terms: 18r + 6 = 16r - 18Subtract 16r on both sides: 2r + 6 = -18Isolate r term: 2r = -24Isolate r: r = -12my picture is my question

2(4x-11)+=19 explain how to do this equaition
Answer:
You'd distribute the 2 to everything in the parenthesis. So, you'd do 2(4x) - 2(-11), which would then be 8x - (-22) = 19. You'd then add 22 to 19 to get 41. The only thing you can do from here is divide 8x by 41 to get 41/8 = x

Solve hurry now please
circles unit
geometry
please help
==========================================
Explanation:
AB is a diameter of the circle with point O in the center. This makes angle AOB to be 180 degrees. Consequently, arc ADB makes up 180 degrees of a full 360 degree circle (ie it makes up half of the circle since 180/360 = 1/2)
We're told that arc ADB is 15pi units long. Since arc ADB makes up half the circle, the full circle must therefore be 2*15pi = 30pi. This is the circumference.
------------------
We're also told that angle COB is 60 degrees. Let's find angle COA
(angleCOA) + (angleCOB) = 180
angleCOA = 180-(angleCOB)
angleCOA = 180-60
angleCOA = 120
Angle COA is 120 degrees
This makes up 120/360 = 1/3 of the full circle
So (1/3)*(circumference) = (1/3)*(30pi) = 10pi is the arc length of AC where we take the shorter path from A to C along the circle's edge.
Answer:
AC = 10π
Step-by-step explanation:
Consider arc ADB with length 15π
ADB = circumference of circle × fraction of circle , that is
2πr × [tex]\frac{180}{360}[/tex] = 15π
2πr × [tex]\frac{1}{2}[/tex] = 15π
πr = 15π ( divide both sides by π )
r = 15
∠ AOC = 180° - 60° = 120° ( adjacent angle to 60° )
Thus
AC = 2πr × [tex]\frac{120}{360}[/tex]
= 2π × 15 × [tex]\frac{1}{3}[/tex]
= 30π × [tex]\frac{1}{3}[/tex]
= 10π
If a car travels an average of 41 mph for 5.2 hours, how far will it travel?
Answer:
It will travel 213.2 miles.
Step-by-step explanation:
Multiply 41 by 5.2
There are 213.2 miles a car travel with an average of 41 mph in 5.2 hours.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
An average speed of a car = 41 mph
And, Time taken by car = 5.2 hours
We know that;
⇒ Speed = Distance / Time
Substitute all the values, we get;
⇒ 41 = Distance / 5.2
⇒ Distance = 41 × 5.2
⇒ Distance = 213.2 miles
