Answer:
JK+KL=JL
Step-by-step explanation:
- (x-6) +(2x-8) =16
- x-6+2x-8=16
- x+2x=16+6+8
- 3x=30
- x=30/3
- x=10
- Now KL
- 2x-8
- 2x10-8
- 20-8
- =1<u>2</u><u>(</u><u>A</u><u>)</u><u> </u>
8x + 2y = 44
5x + 2y = 35
Since 2y is already common, there is no need for multiplication. Just reverse the signs on the equation.
Like this;
8x + 2y = 44
-5x - 2y = -35
All the additions become subtractions and vice versa.
-2y and +2y get cancelled.
Leaving;
8x = 44
-5x = -35
Now, subtract again.
8x - 5x = 3x
44 - 35 = 9
So;
3x = 9
x = 9 / 3
x = 3
We found 'x' and now we have to find 'y'.
Just substitute.
[8 x 3] + 2y = 44
24 + 2y = 44
2y = 44 - 24
2y = 20
y = 20 / 2
y = 10
Now, we re-check;
[8 x 3] + [2 x 10] = 44
24 + 20 = 44
Explaining the error for #9b is simply doing the whole sum.
Hope this helped! :) I tried my best to explain.
Answer:
Angles A and E
Step-by-step explanation:
If you see the angles size you would see that A and E are in opposite sides meaning it would be the same so Angles A and E are the same
we have
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
therefore
the answer is
