Solve for x:
x^2 + 10 x + 12 = 36

36 = 36:
x^2 + 10 x + 12 = 36

Subtract 12 from both sides:
x^2 + 10 x = 24

Add 25 to both sides:
x^2 + 10 x + 25 = 49

Write the left hand side as a square:
(x + 5)^2 = 49

Take the square root of both sides:
x + 5 = 7 or x + 5 = -7

Subtract 5 from both sides:
x = 2 or x + 5 = -7

Subtract 5 from both sides:
Answer:  x = 2 or x = -12 Thus the Answer is A.

The two box-and-whisker plots below show the scores on a math exam for two classes. What do the interquartile ranges tell you ab
Neko [114]
The interquartile range is a measure that indicates the extent to which the central 50% of values within the data set are dispersed.
The interquartile range: Upper quartile - Lower quartile
As we can see in the box-and-whisker plots:
Class A:  89-66 = 23
Class B: 94-79 = 15
This shows that the spread in the scores of class A within the central 50% of values is higher than the spread of the scores of the class B.

Are associative properties true for all integers
faust18 [17]
The answer is "yes" for all integers.

This property is mainly used to either simplify the expressions or to group alike terms together. It is applicable only for operations of addition and multiplication.

Examples:
57x + 94 xy = x (57+94y)
2ab - 6abc = 2ab (1-3c)

What is 1800 in its corresponding exponential form
pav-90 [236]

The formula for exponential form is:

e^x = y

Where, y in this case is 1800, e is exponential, and we are to find e^x.

e^x = 1800

To find for x, we have to multiply both sides with the natural log, ln.

ln (e^x) = ln (1800)

x ln e = ln (1800)

<span>ln e = 1 and by using the calculator,</span>

x = 7.496 = 7.5

<span>Therefore the exponential form of 1800 is e^7.5</span>

<span>ANSWER: </span>e^{7.5}
