Pleas help and only answer if you know it and put the number by which one you answer

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)

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.

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.

Answer:

The length of each part is 3.5 inches.

Step-by-step explanation:

The question states that the bar is 7 inches long, with the two parts being equal lengths.

What you would do to find the length of each bar is doable with simple division. Take 7, and divide it by 2. 2 goes into seven 3 times, which would leave 1. Add a decimal and a zero, bring the zero down, and you get 10. 2 goes into 10 five times, giving you the 5 in 3.5.

1/2×7=3.5 inches is the equation which gives the length of the one of the part of bar.

The area of Rectangle is length times of width.

Given that the bar is 7 inches long and divided into 2 equal parts.

We need to find the length of one of those parts.

We take the whole bar as a whole number.

The two parts of the bar are considered as parts of the bar.

The seven inches is divided equally.

The length of the bar is seven inches.

We need to divide seven by two to get the length of one part.

When seven is divided by the two we get three point five inches which is the length of the one of the part of the bar.

1/2×7=3.5 inches

The equation which gives the length of the one of the part of bar is 1/2×7=3.5 inches.

Hence, 1/2×7=3.5 inches is the equation which gives the length of the one of the part of bar.

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

Explanation:

For now, let's ignore the 73 pounds.

The 13 ounces she gains is added onto the initial 3 ounces to get 3+13 = 16 ounces = 1 pound.

So we add this 1 pound onto the 73 pounds from earlier to get the answer to be 73+1 = 74 pounds

-----------------

We could write the steps out like this

(73 pounds, 3 ounces) + (13 ounces)

(73 pounds + 3 ounces) + (0 pounds + 13 ounces)

(73 pounds + 0 pounds) + (3 ounces + 13 ounces)

73 pounds + 16 ounces

73 pounds + 1 pound

74 pounds

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.

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
