If a = 10, then the equation would be 10+6.
The answer would be 16.
Hope this helps! :D
Answer:
(5x+12) (5x-12)
Step-by-step explanation:
Use the difference of squares fromula. 
Where a = 5x and b =12.
Okay, you would need to distribute it.
It would be 3/4x - 3/4 = 10/8x - 20/8
Answer:
Step-by-step explanation:
If you round 4.3 to the nearest whole number, you will get 4.The reason is because a number less than 5 is closer to 4 but a number greater than five or is five will be rounded to five.

Answer:
X=58 degrees
Step-by-step explanation:
So We can start by finding the angle thats supplementary to 109.
Well 109 and another unknown angle (which will be Y for this scenario) would form a straight line which is 180 degrees.
109+y=180
Solve that by isolating the y and you would get 71 as the missing side.
Now we have 2 sides, 71 and 51. We’re trying to find x or the angle vertical to the thrid interior angle of the triangle.
Vertical is basically equal so we really just gotta find the third side. A triangle is equal to 180 degrees and if you add em up.
71+51+x=180
Combine like terms
122+x=180
Isolate the X
x=58
So x is 58 degrees.
