6x² - 20x + 6
Step-by-step explanation:

Answer:
Step-by-step explanation:
4x - 13 = 2x + 9
4x - 2x = 9 + 13
2x = 22
x = 22/2
x = 11 <===
Answer:
Step-by-step explanation:
I need the rest of the question. What are the choices?
7/8= 7 divided by 8 = 0.87
0.87 divided by 2 = 0.43
0.43= 43/100 OR you can say 3/7 as well but it's 0.42,but when rounded it 0.43..
Answer:
x = 20
Step-by-step explanation:
I don't see a y in the diagram.
The 3 angles x, 90 and (4x - 10) lie on the line EF and sum to 180°, so
x + 90 + 4x - 10 = 180, that is
5x + 80 = 180 ( subtract 80 from both sides )
5x = 100 ( divide both sides by 5 )
x = 20
