Step-by-step explanation:
The algebraic expression is
(x²+ 7x+10/ x²+ 4x+4 ) (x²+ 3x+2/x²+ 6x+5)
The options are Arrangement
a.(x+5/x+2) * ( x+2/x+5) Number 2
b.(x+7/x+4) ( x+1/x+2)
c. 1 Number 4
d. (x+5) ( x+2) /(x+5)

g. x+2
h.(x+5/x+2) ( x+2/x+5) Number 3
Answer
Factorizing the expressions (x²+ 7x+10/ x²+ 4x+4 ) (x²+ 3x+2/x²+ 6x+5)
=(x²+ 5x+2x+ 10/ x²+ 2x+2x+4 ) (x²+ 2x+x+ 2/x²+ 5x+x+5)
Taking common
=[x(x+5) +2(x+5)/ x(x+2) +2(x+2) ] [ x(x+2) +1(x+2)/ x((x+5) +1(x+5)]
Putting commons together
=[(x+2) (x+5)/ (x+2) (x+2)] [ (x+2)(x+1)/ (x+1) (x+5)]
Cancelling
= [ (x+5)/ (x+2)]* [ (x+2)/ (x+5)]
=[ (x+5)/ (x+2)] [ (x+2)/ (x+5)]
Again Cancelling
=1
The above question is solved in 4 steps :
Step 1
(x+2) (x+5)/(x+2) ( x+2) * (x+1) (x+2)/(x+5) ( x+1)
Step 2
(x+5/x+2) * ( x+2/x+5)
Step 3
(x+5/x+2) ( x+2/x+5)
Step 4
1 which is the answer .
The steps
(x+7) (x+1)/(x+4) ( x+1) * (x+3) (x+1)/(x+3) (x+2) ,
(x+5) ( x+2) /(x+5),
(x+7/x+4) ( x+1/x+2) and (x+2) are not related to this question.

BD is the angle bisector of ZABC.
If m ABD=25° find m/DBC.
A:50°
B:25°
C:750
D:100°
Answer:
B:25°
Step-by-step explanation:
Now [tex]\angle ABC[/tex] gets bisected by [tex]BD[/tex].
[tex]\angle ABD=25^{\circ}[/tex]
Since, the angle is bisected, this means that the angle is split into two equal parts or the angle is halved.
We know that one of the angles is [tex]25^{\circ}[/tex] so the other angle has to be [tex]25^{\circ}[/tex] also.
Hence, the [tex]m\angle DBC=25^{\circ}[/tex].

High school text books don't last forever. The lifespan of all high school statistics textbooks is approximately
normally distributed with a mean of 9 years and a standard deviation of 2.5 years. What percentage of the
books last more than 10 years?
34.5%
84.5%
O O O O O
65.5%
11.5%
69%
Answer:
34.5%
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 9, \sigma = 2.5[/tex]
What percentage of the books last more than 10 years?
As a proportion, this is 1 subtracted by the pvalue of Z when X = 10. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{10 - 9}{2.5}[/tex]
[tex]Z = 0.4[/tex]
[tex]Z = 0.4[/tex] has a pvalue of 0.655
1 - 0.655 = 0.345
So
34.5% of the books last more than 10 years.

A recipe for ten flapjacks needs 20g butter, 30g
sugar and 50g rolled oats. How many flapjacks can
I make if I have 140g butter, 150g sugar and 200g
rolled oats?
Answer:
49
Step-by-step explanation:
For 10 flapjacks we need a total of 100g of ingredients
therefore, we need to get how many gram for 1 flapjacks
that is, for butter 20÷10=2
for sugar 30÷10=3
for rolled oats 50÷10=5
that's a total of 10.
this means it takes 10g of ingredients to make 1 flapjacks
then 140+150+200=490
490÷10=49
The final answer is 49 flapjacks can be made from the above ingredients
What is the distance between A and B?
The formula in finding the distance between two points is given below:
[tex] \boxed{\bold{\:\:d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \:\:}}[/tex]Now, you know the distance formula. So, let us try solving the given problem using the distance formula.
Problem: What is the distance between A(-3, -4) and B(4, 5)?
From inspection on the given problem:
[tex]\sf (x_1, y_1) = (-3, -4)[/tex][tex]\sf (x_2, y_2) = (4, 5)[/tex]Substitute the given values into the distance formula and solve for AB:
[tex]\sf AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex][tex]\sf AB = \sqrt{[4 - (-3)]^2 + [5 - (-4)]^2}[/tex][tex]\sf AB = \sqrt{(7)^2 + (9)^2}[/tex][tex]\sf AB = \sqrt{49 + 81}[/tex][tex]\bold{AB = \sqrt{130} \approx 11.4 \: units}[/tex]Therefore, the distance between two points is [tex]\sqrt{130}[/tex] or 11.4 units.

A weather station on the top of a mountain reports that the temperature is currently 0°C and has been folling at a constant rate of 3°C per hour. Find each temperature. Explain or show your reasoning.
Answer:
Step-by-step explanation:
This question is incomplete; here is the complete question.
A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate of 3°C per hour. Find each temperature. Explain or show your reasoning.
If it continues to fall at this rate, what will the temperature be:
In 2 hours ............. In 5 hours .............. In half an hour......................
If the current temperature of the mountain is b°C and it is falling at a constant rate of 3°C per hour.
Then after 'x' hours, temperature on the top of the mountain will be represented by the function,
T(x) = 0 - 3x
Therefore, temperature after 2 hours = -3(2) = -6°C
Temperature after 5 hours = -3(5) = -15°C
Temperature after half an hour = [tex]-3(\frac{1}{2})[/tex]
= -1.5°C

Determine the value of y, if x is –10.
y = |x| – 11
Answer:
y = -1
Step-by-step explanation:
The two lines around x is the absolute value symbol. Absolute value is how far away a number is from 0 on a number line. -10 is 10 points away from 0, so it is now 10.
y = 10 - 11
y = -1
SOLVE FOR Y, WILL GIVE BRAINLIEST
Answer:
Step-by-step explanation:
1. As you can see in the picture, x is 116 degrees, because that angle and the angle labeled 116 degrees are corresponding, meaning that their angles are the same.
2. As you can also see in the picture, y+11+x = 180 deg, because they are two angles that make a straight angle. We know that x is 116 deg, so we can solve y with an equation:
y + 11 + 116 = 180
y + 127 = 180
y = 180 - 127
y = 53 degrees.
