Please help I’m confused math is hard!
Answer:
Step-by-step explanation:
basically, what they are asking you is to factor and then plug in the values (x=3; x=4) that they gave you.
first, you need to factor out the equation.
start with the original equation.
V=4x^3+10x^2+4x
factored form:
V= 2x(2x^2+5x+2)
next, you're going to want to plug in the values.
the answer asks for x=4, but you should do both.
v=2(3)(2(3)^2+5(3)+2)
do not forget to do the exponents before!
v=6(18+15+2)
v=6(35)
v=210 ft^2
that's the answer for if x was equal to 3.
V= 2x(2x^2+5x+2)
don't forget to write the original equation first.
V=2(4)(2(4)^2+5(4)+2)
V=8(36+20+2)
V=464 ft^2⬆is your answer! hope this helped!!

Geometry Question! !

Please don't answer if you don't know! Or I'll report you!
Thanks in advance :)
I'll answer question 2
Answer: 600,000 square miles
Note: you may need to erase the comma if you are typing this answer into a computer system.
===============================================
Explanation:
Draw a line segment from point B to point D. This divides the quadrilateral into two triangles ABD and BCD.
Refer to the attached image below. First look at figure 1.
This shows triangle ABD with base AD = 800 and height 300. The height is the vertical distance from point B to the x axis. Note how point B is 300 units above the x axis. The height is shown in blue, and the height is always perpendicular to the base.
The area of triangle ABD is...
area = (base*height)/2 = (800*300)/2 = 120,000 square miles
We'll use this later.
---------------------------------
Now refer to figure 2 in the attached images.
This shows triangle BCD. It has base CD = 800. It might help to rotate the triangle so that CD is horizontal. The height, shown in blue, is perpendicular to the base. It is 1200 units because we span from x = -800 to x = 400 which is a total horizontal distance of |-800-400| = 1200
The area of triangle BCD is....
area = (base*height)/2 = (800*1200)/2 = 480,000 square miles
---------------------------------
Lastly, we'll add up the two triangular areas we found
area of quadrilateral ABCD = (area of triangle ABD) + (area of triangle BCD)
area of quadrilateral ABCD = (120,000 sq mi) + (480,000 sq mi)
area of quadrilateral ABCD = 600,000 square miles

Triangle JKL is equilateral. All three interior angles have equal measures.
What is the measure of exterior angle 1?
30 degrees
60 degrees
120 degrees
130 degrees
Answer:
C. 120º
Step-by-step explanation:
so we know that the inside of a triangle is 180º and since all the measures are the same we can do 180/3 to find how much each angle is.
180/3 = 60º
now we also know that a straight line is equal to 180º and since we already have one angle, all we have to do is subtract 60 from 180.
180 - 60 = 120º

Answer: 0.25 ( so I think you put it in between 0.2 and 0.3)
Step-by-step explanation:
There is a total of 4 counters.
so 1/4 = 0.25
The amount of white counters would be 0.75
and the amount of black would be 0.25
This would give the total probability
Answer:
0.25
Step-by-step explanation:
Since there is only one black in a total of four counters you would right it as 1/4 in equation form. In the decimal form, you would write it as 0.25. So, that means that you would put the cross in between 0.2 and 0.3.
Hope this helps :)

ypu just need help thxsssss
Answer:
16/8
Step-by-step explanation:
All you have to do to calculate the size of the new shape is take both numbers and multiply them by 4
The width is 4 inches, so
4x4=16
The height is 2 inches, so
2x4=8
If you're wanting to calculate the area of the new shape, just multiply 16 by 8.
16x8=128
If you need to calculate the perimeter of the shape, do this
16+16+8+8=48.
Hope this helped!
Thanks!

Will the graph of the line represented by the table intersect the graph of y = 5x + 4? Explain.A table showing data of x and y as (-2,5), (-1,0), (0,5), (1,10) and (2,15) respectively.
Answer:
you'll need to identify the equation of the line represented in the table. By plugging in coordinates given in the table, it's possible to identify the slope and y-intercept of the line.
Step-by-step explanation:
Yes, the lines intersect each other.
What is slope?The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.
Given that, a table of points (-2,5), (-1,0), (0,5), (1,10) and (2,15) and a line
y = 5x + 4
Finding the slope of the line represented by the given points,
slope = (y₂-y₁)/(x₂-x₁)
Considering the points (-2,5) and (-1,0)
Slope = (0-5)/(-1+2) = -5/1 = -5
And the slope of the line y = 5x + 4 is 5
We know that, If they have different slopes and different y-intercepts, they will meet at a point.
Hence, the lines will intersect.
