Hey There Baby and, Welcome to Brainly
<span>Which equation has the same solution as x²- 6x - 12 = 0
</span><span> x^2 - 6x = 12 </span>
<span>
x^2 -6x + 9 = 12+9 </span>
<span>
x^2 -6x + 9 =21 </span>
<span>
(x-3)^2 = 21
</span>
So the answer will be <span>(x-3)^2=21 </span>
Answer:
y = 50
Step-by-step explanation:
All triangle angles add up to 180 degrees.
To set this equation up, you need to add everything given in the triangle and set it equal to 180:
y + y + 80 = 180
<em><u>Add like terms:</u></em>
2y + 80 = 180
<u><em>Subtract 80 from both sides:</em></u>
2y + 80 = 180
- 80 - 80
___________
2y = 100
<u><em>Divide both sides by 2:</em></u>
y = 50
<u><em>If you're unsure, you can plug in the 50 for y:</em></u>
y + y + 80 = 180
50 + 50 + 80 = 180
100 + 80 = 180
180 = 180
Answer:
74.9018
Step-by-step explanation:
happy holidays and have a nice day!
12 3/5, 12.7, 12 3/4
12 3/5 = 12.6
12 3/4 = 12.75
No error - A and B are completely right, and using the subtraction law D is right
