Answer:
Angle A = 30.8
Angle B = 33.2
Step-by-step explanation:
180 - 116 = 64
This means that the other two angles need to add up to 64.
I just plugged in numbers until it worked.
I got that x = 14.6
2x + 4
2(14.6) + 4
29.2 + 4
33.2
3x - 13
3(14.6) - 13
43.8 - 13
30.8
Those are your angles. To make sure they are correct you just need to add up all the angles and make sure that they equal to 180.
116 + 33.2 + 30.8 =
180
Answer:
A. x > -1
Step-by-step explanation:
- (x - 3) < 4 (2 + x)
-x + 3 < 8 + 4x
-5x + 3 < 8
-5x < 5
x > -1
Therefore, answer choice A is the correct answer.

<em>The value of a correlation coefficient ranges between -1 and 1.</em>
<em />
<em>The greater the absolute value of the Pearson product-moment correlation coefficient, the stronger the linearrelationship.</em>
<em />
<em>The strongest linear relationship is indicated by a correlation coefficient of -1 or 1.</em>
<em />
<em>The weakest linear relationship is indicated by a correlation coefficient equal to 0.</em>
<em />
<em>A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.</em>
<em />
<em>A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.</em>

Answer:
x² + 7x + 10 = 0
Subtract 10 from both sides
x² + 7x = -10
Use half the x coefficent (7/2) as the complete the square term
(x + 7/2)² = -10 + (7/2)²
note: the number added to "complete the square" is (7/2)² = 49/4
(x + 7/2)² = -10 + 49/4
(x + 7/2)² = 9/4
Take the square root of both sides
x + 7/2 = ±3/2
Subtract 7/2 from both sides
x = -7/2 ± 3/2
x = {-5, -2}
