Find awnsers 7- 12
not sure how to do slopes :/
factor each polynomial
ok so
leave y^2 alone
so you need to get 2 factors that when added equal 11 so 9x2=18
and 9+2=11
so it would be (y+9)(y+2)
hope this helps

The perimeter of the polygon is_______units.
Answer:
3 units
Step-by-step explanation:
Since the sides are congruent, then
5 - 2x = - 4x + 9 ( add 4x to both sides )
5 + 2x = 9 ( subtract 5 from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
Then
5 - 2x = 5 - 2(2) = 5 - 4 = 1
perimeter = 3 × 1 = 3 units

Jayce looks around at an assembly. He notices his younger sister to his right and his older brother 48 feet ahead of him. If Jayce's brother and sister are 52 feet apart, how far apart are Jayce and his younger sister? *
Answer:
Solution given:
base[b]=48ft
perpendicular [p]=52ft
hypotenuse[h]=?
By using Pythagoras law
h²=p²+b²
h²=48²+52²
h=√5008
h=70.767=7.8ft
Jayce and his younger sister is 7.8ft apart.
can some one multiply (x+11)^2

Your math test scores
are 81%, 77%, 79%,
83%, and 70%. Which
measure of central
tendency should tell
your parents to make
your math test scores
seem highest?
Answer:
Median
Step-by-step explanation:
Mean: (81+77+79+83+70)/5 = 78
Median: 70, 77, 79, 81, 83
Mode: None
Therefore, the median is the better measure of central tendency you should tell your parents to make your math test scores seem highest.
Answer:
if you choose mean, your score would be 78 because 81+77+79+83+70=390, divide that by 5 and you get 78, your median would be the 79, and if you choose mode, you really couldn't calculate it since there is only one of each number, therefore the best choice is the median of 79%

Complete the sentence the length of a segment from a vertex to the centroid is the length of the median from that vertex
Answer:
The length of a segment from a vertex to the centroid is
“ 2/3 “ the length of the median from that vertex
Hence, the length of the median from that vertex is [tex]\frac{2}{3}[/tex].
What is the vertex?
The common endpoint of two or more rays or line segments Vertex typically means a corner or a point where lines meet.
Here given that,
The length of a segment from a vertex to the centroid is the length of the median from that vertex.
So, the length of a segment from a vertex to the centroid is [tex]\frac{2}{3}[/tex] which is the median of that vertex.
Hence, the length of the median from that vertex is [tex]\frac{2}{3}[/tex].

A survey of students at a large high school reveals that 59% of the students are studying a language other than English. The options for language study at the school include Spanish, French, Japanese, and American Sign Language (ASL). Currently, 6% of the students who study a language other than English are studying ASL.
Suppose we select a student from the survey at random. Given that the student is studying a language other than English, what is the probability that the person is studying ASL?

A student has scores of 73, 84, 91 and 78. What score must the student earn on the fifth test in order to have an average score of 85?
A. 85
B. 88
C. 97
D. 99
Answer:
[tex]99[/tex]
Step-by-step explanation:
The average of an [tex]x[/tex] amount of values is equal to the sum of all the values divided by [tex]x[/tex]. Thus, for any five scores to have an average score of 85, the sum of the scores must be [tex]85\cdot 5=425[/tex]
Therefore, we have the following equation:
[tex]73+84+91+78+m=425,\\m=\boxed{99}[/tex]
4x = 2(x-5)-2 can you solve please
Answer:
x = -6
Step-by-step explanation:
4x = 2(x-5)-2
2 * x = 2x
2*-5 = -10
4x = 2x - 10 -2
4x = 2x - 12
4x - 2x = 2x
2x = -12
-12/2 = -6
x = -6

Answer:
The length would be 1.5x + 5.
Step-by-step explanation:
So first with this, note that 2 length + 2 height gives the perimeter of the rectangle.
Given this:
2(1/2x + 4) + 2(?) = 4x+18
x+8 + 2(?) = 4x+18
2(?) = 3x+10
? = 1.5x+5
1.5x + 5 = 1.5x + 5
The length would be 1.5x + 5.
To double check, by plugging in 1.5x + 5 back into the equation for the perimeter, you will get the same perimeter:
2(1.5x + 5) + 2(1/2x+4) = P
3x+10 + x+8 = P
4x + 18 = P
Emily makes cylindrical bars of soap to sell online. Each bar has a radius of 3.5 cm and a length of 4 cm. Each bar is wrapped in plastic before shipping. In terms of π, how much plastic will Emily need to ship 20 bars of soap?
A) 52.5π cm2
B) 110π cm2
C) 1050π cm2
D) 1075π cm2
Answer:
C) 1050π cm²
Step-by-step explanation:
Surface area of a cylinder = 2πrh + 2πr²
radius, r = 3.5cm
Height, h = 4 cm
Surface area of a cylinder = 2πrh + 2πr²
= 2 * π * 3.5 * 4 + 2 * π * 3.5²
= 28π + 2π * 12.25
= 28π + 24.5π
= 52.5π cm²
Surface area of a cylinder = 52.5π cm
There are 20 bars of soap
Total plastic Emily needs for 20 bars of soap = surface area of each soap × 20
= 52.5π cm² × 20
= 1,050π cm²
A 50-meter cable is secured at the top of the tower and tied 30 meters away from
the base. What angle does the cable form with the ground?
Answer:
53.13 degrees to the nearest hundredth.
Step-by-step explanation:
We know the adjacent side and the hypotenuse of the right triangle.
So cos x = 30/50 = 0.6
The required angle x = 53.13 degrees.
A triangular prism has a height of 11 meters and a base with the following measurements. All dimensions are in meters.
