Answer:
Step-by-step explanation:
The median is the average of the lengths of the two bases:
5x -20 = (12 + (4x -10))/2
5x -20 = 2x +1
3x = 21 . . . . . add 20-2x
x = 7
Then the lengths are ...
median = 5x -20 = 5·7 -20 = 15
base = 4x -10 = 4·7 -10 = 18

<u>How can </u><u>we</u><u> factor 5x^2 + 26x - 24 = 0 using the completing the square </u><u>method?</u>
Let's solve your equation step-by-step.
First, add 24 to both sides.
Since the coefficient of 5x² is 5, divide both sides by 5.
The coefficient of 26/5x is 26/5. So, let b=26/5.
Then we need to add (b/2)²=169/25 to both sides to complete the square.
Add 169/25 to both sides.
Factor the left side.
Take square root.
Then, add (-13)/5 to both sides.

Answer: Let's solve for x.
2x−10y=10
Step 1: Add 10y to both sides.
2x−10y+10y=10+10y
2x=10y+10
Step 2: Divide both sides by 2.
2x
2
=
10y+10
2 answer
x=5y+5
Step-by-step explanation:
Let's solve for s.
sx+9y=9
Step 1: Add -9y to both sides.
sx+9y+−9y=9+−9y
sx=−9y+9
Step 2: Divide both sides by x.
sx
x
=
−9y+9
x
s=
−9y+9
x
Answer: hope this helps:)
s= -9y+9/x
The sum of interior angles = (n-2) x 180 where n is the number of sides
