<h2>Steps</h2>
So firstly, we need to isolate the x terms onto one side. To do this, subtract 48 on both sides of the equation:
Next, divide both sides by 2:
Next, we are gonna make the left side of the equation a perfect square. To find the constant of this soon-to-be perfect square, divide the x coefficient by 2 and then square the quotient. Add the result onto both sides of the equation:
Now, factor the left side:
Next, square root both sides of the equation:
Next, add 5 to both sides of the equation:
Lastly, solve the left side twice -- once with the plus sign and once with the minus sign.
<h2>Answer</h2>
<u>In short, x = 6 and 4</u>
Answer:
2. congruent
3. congruent
Step-by-step explanation:
Segments will be congruent if their lengths are the same. Their lengths will be the same if the sum of squares of the x- and y-differences of their endpoint coordinates are the same.
2. B-A = (-4-(-4), 8-1) = (0, 7)
D-C = (5-(-2), -5-(-5)) = (7, 0)
The total of 0² and 7² is the same as the total of 7² and 0², so these segments are congruent. (They are both of length 7.)
__
3. B-A = (2-4, 6-1) = (-2, 5)
D-C = (-4-(-2), -3-2) = (-2, -5)
The sum of (-2)² and 5² is the same as the sum of (-2)² and (-5)², so these segments are congruent. (They both are of length √29.)
Answer:
9
Step-by-step explanation:
40% of 15 = 6.
1/6 of 18 = 3.
6 + 3 = 9.
The answer is x=2/3!! Hope this helped
