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

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
can some one multiply (x+11)^2

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.

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
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
Answer:
Step-by-step explanation:
(x + 9 ) ( x + 2 )

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.

y = x² – 4 y = 2r + 4
Solve algebraicallu for the solutions of equations below.
Step-by-step explanation:
Okay, the first step is to rewrite this equation in "vertex form." You can search that up but it's basically just (h/k).
y = ( x − 1) 2 + 3
Now, we are going to use the vertex form, "y = a (x - h)2 + k, to get the values of a, h, and k.
By using the form we get 1 for the value a, 1 for the value h, and 3 for the value k.
1 = a
1 = h
3 = k
Becuse the value of a is positive, the parabola opens up! (A parabola is the U shaped line in a graph, so that opens up.)
Now, we find the vertex (h,k)
which is (1,3)
Now we find the p from the vertex to the focus. (vertext the top, focus one of the points.)
Follow this formula to find the distance from the vertex to a focus by using this formula
1/4a.
Now we just gonna substitue 1 for a, since we know that 1 equals a above ^
1/4 * 1
Solving that, we got a nice little 1/4.
Next we find the focus
"Find the focus.
The focus of a parabola can be found by adding p to the y-coordinate k if the parabola opens up or down.
(h,k+p)
Substitute the known values of h, p, and k into the formula and simplify.
(1,134)
Find the axis of symmetry by finding the line that passes through the vertex and the focus.
x=1
Find the directrix.
y=114
Use the properties of the parabola to analyze and graph the parabola.
Direction: Opens Up
Vertex: (1,3)
Focus: (1,134)
Axis of Symmetry: x=1
Directrix: y=114
Select a few x values, and plug them into the equation to find the corresponding y values. The x values should be selected around the vertex.
xy−1704132437
Graph the parabola using its properties and the selected points.
Direction: Opens Up
Vertex: (1,3)
Focus: (1,134)
Axis of Symmetry: x=1
Directrix: y=114

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%
