Answer 1

Answer:

$40

Step-by-step explanation:

He bought the pencils for $10, so his expense was $10. He sold the pencils for $50, and $50 - $10 is $40, and that's the total amount of money he made.

multiply it using a calculator

Answer:

144 ft^2

Step-by-step explanation:

Here we have a trapezoid with a triangle inside.

The legs of the trapezoid are 18 ft and 8 ft, and so the average length of the trapezoid is (18 + 8)/2 ft, o 13 ft.  The total area of the trapezoid is thus:

A = (13 ft)(16 ft) = 208 ft^2

Now we must find the area of the white triangle and subtract it from the area of the trapezoid already found.  The area formula for a triangle i

A = (1/2)(base)(height), which in this case is A = (1/2)(8 ft)(16 ft), or

A = 64 ft^2.

Subtracting the area of the triangle from that of the trapezoid yields

Area of figure = 144 ft^2

A triangle has one angle that measures 26 degrees, one angle that measures 47 degrees, and one angle that measures 107 degrees.

(2m-7)(2m-7)
4m^2 - 14m - 14m + 49
4m^2 - 28m + 49

Answer: 4m²-28m+49

Step-by-step explanation:

(2m-7)² can be written as (2m-7)(2m-7).

You would have to multiply it out like this:

2m times 2m=4m² (2x2=4 and mxm=m²)

2m times -7=-14m (2x-7=-14 then put a m on it)

-7 times 2m=-14m

-7 times -7=49

The equation would then look like this:

4m²-14m-14m+49

Then you would have to collect like terms. Like terms are terms with the same variables and powers. It will then look like this:

4m²-28m+49

Answers

Answer:

The answer is "C"

Step-by-step explanation:

Answer:

Answer C.  This point lies between the two axes and its coordinates satisfy both equations

Step-by-step explanation:

Line A: y = x − 4

Line B: y = 3x + 4

Let's actually solve this system, using substitution:  Equate

Line A: y = x − 4   to   Line B: y = 3x + 4, obtaining:

                  x − 4  =     3x + 4

Subtract (x - 4) from both sides.  Doing so yields

                         0 = 2x + 8, and so x = -4.

From Line A let's find y:   Letting x = -4, we get:  y = -4 - 4 = -8

and so the solution is (-4, -8).  This matches Answer C.  This point lies between the two axes and its coordinates satisfy both equations.

Answer:

The degree of this polynomial is 3.

Step-by-step explanation:

Hey!

==================================================================

When a polynomial has more than one variable, we need to look at each term to find out what the degree is. Terms are separated by + or - signs.

Find the degree by adding the exponents of each variable in it,

The largest such degree is the degree of the polynomial.

Let's start out by finding the degrees for each terms:

3x³ = The degree, or exponent, of x is 3.

5x² =  The degree, or exponent, of x is 2.

1 = Constant Terms do not have a degree.

So, since the largest degree of a term is the degree of the polynomial., The degree of this polynomial is 3, since that is the highest!

Answers

Answer:

Let me figure it out rq hold on

how to find the surface area:

The surface area of the triangular prism is the sum total of the areas of its bases and its lateral faces,

736 square feet

We have 2 triangles to add and 3 rectangles.
Area of a rectangle is length x width.
Area of a triangle is 1/2 x base x height.

The top 2 rectangular sides are 20 x 10 = 200 each = 400 total.
The bottom rectangle is 20 x 12 = 240
The triangles are each 1/2 x 12 x 8 = 48, and there are 2 triangles, = 96


Add them all up: 400 + 240 + 96 = 736 square feet

Help me answer the four questions on the left pls!

Answers

Answer:

l = 14

Step-by-step explanation:

The perimeter of a rectangle is

P =2(l+w)

The width is x-6

w = x-6

The length is 8 units longer than the width

l = w+8

l = x-6+8

l = x+2

We can substitute this into the equation for Perimeter, which is given as 40

40 = 2(x+2 + x-6)

Combine like terms

40 =2 (2x-4)

Divide by 2

40/2 = 2/2 (2x-4)

20 = 2x-4

Add 4 to each side

20+4 =2x-4+4

24 = 2x

Divide by 2

24/2 =2x/2

12=x

We want to know the length

l = x+2

l =12+2

l = 14
