We have that
x²<span>-6x+7=0
</span>Group terms that contain the same variable
(x²-6x)+7=0
Complete the square Remember to balance the equation
(x²-6x+9-9)+7=0
Rewrite as perfect squares
(x-3)²+7-9=0
(x-3)²-2=0
(x-3)²=2
(x-3)=(+/-)√2
x=(+/-)√2+3
the solutions are
x=√2+3
x=-√2+3
Answer:
x= 13
both angles are equal to 106
Step-by-step explanation:
8x + 2= 14x - 76
-8x +76 - 8x +76
78 = 6x
78/6 = 13
8 (13) + 2 = 104 + 2 = 106
14(13) - 76 = 182 - 76 = 106
Answer:
B=58
Step-by-step explanation:
Complementary angles are angles where the sum equals 90°. So all you have to do is 90-32 and you get 58.
