Answer: x2 + 4x + 11
Step-by-step explanation:
(x + 2)2 + 7
(x+2)(x+2) + 7
X2 + 2x + 2x + 4 + 7
x2 + 4x + 11
Answer:
A can paint in 3days and B in 6 days
Step-by-step explanation:
From the question we were told
Person A can paint the neighbors house 2 times as fast as Person B
Let A only paint the neighbors house in X days
Let B only paint the neighbors house in 2X days
If we express the given information from the question in terms of fraction we have,
1/X + 1/2X = 1/2
3/2X = 1/2
if we cross multiply we have
6= 2X
X= 6/2
X= 3
Then A can paint the house in 3 days and B in 2(3)= 6days.
In this case, we will use our Pythagorean Theorem.
a = 84
b = 13
c = x
Thus,
x = 85.
<DSR + <SRD + <RDS = 180° (Angle sum property)
2x + x +3x = 180°
6x = 180°
x = 180°/6
x = 30°
So, <SRD = x = 30°
<RDS = 3x = 3(30°) =90°
<DSR = 2x = 2(30°) = 60°
Hope it helps !

Answer:
the answer would be A. a measure of center, such as the median
Step-by-step explanation:
A measure of center for a numerical data set summarizes all of its values with a single number, while a measure of variation describes how its values vary with a single number.
Some examples of a measure of center are median and mode. Some examples of a measure of variation are interquartile range and mean absolute deviation.
The salon manager wants one number to summarize all the values of the data set.
