Hello there!
Here is the answer worked out for you!
12x[-1+sqrt(5)]
-12x+12xsqrt(5)
Remember that you can only add like terms so you can't add -12x to 12xsqrt(5). The radical makes it an unlike term.
I hope this helped and best wishes!
Answer:
x = 6
y = - 14
Step-by-step explanation:

- -2x × 2 + 10 = - 2x - 2
- x = 6
- y = -2 × 6 - 2 = - 14
(2y² + 7y + 11) - (8y² - 5y + 7) you can distribute the negative sign to the second expression and then combine the like terms
new expression: (2y² + 7y + 11) (-8y² + 5y - 7)
2y² and -8y² equals -6y²
7y and 5y equals 12y
11 and -7 equals 4
The answer is -6y² + 12y + 4
Answer:
Step-by-step explanation: 11x-6y=13
Answer:
Correct answer is <em>D. ASA</em>
<em />
Step-by-step explanation:
Let us first define <em>ASA congruence</em> rule:
2 triangles are called congruent according to ASA congruence rule if 2 angles of the triangle and the corresponding side between these two angles are <em>equal </em>to each other.
In the question figure, we can figure out following conclusions from Triangles
respectively:

- Side RS = Side WX
As per the definition of option d) ASA congruence, the triangles are congruent.
