Check my answer!Write the product as a trinomial.

(m - 6)(m + 3)

My answer: m^2 - 9m + 18

Answers

Answer 1
Answer: m x m  =  m ^ 2
m x 3 =    3m
-6 x m =   -6m
-6 x 3 =    -18

adding these you get    m^2 -3m -18
Answer 2
Answer: (m - 6)(m + 3)=\nm^2+3m-6m-18=\nm^2-3m-18

What is the surface area of 10cm 15cm and 10

Answers

The surface area of 10cm, 15cm, and 10cm is found by splitting the dimensions to many different equations. 
1st equation: 10 times 15
2nd equation: 10 times 10 
3rd equation: 10 times 10
4th equation: 10 times 15
5th equations: 10 times 15
6th equation: 10 times 15
You would then add all the solutions up to get the final solution. 
The answer is...
800

Find the surface area of the prism.
It is ___inches squared.

Answers

Answer:

Should be 132 square feet.

Step-by-step explanation:

(Triangle surface area = 1/2 × width × length)

(square surface area = width × length)

Now you just add the surface area of all the faces.

If this is correct pls mark me brainly tyy :).
132 square feet because once you do all of the math it’s 132

the current temperature in smalltown is 20 °F this is 6 degrees less than twice the temperature thst that it was six hour ago what was the temperature is smalltown six hout ago

Answers

2 x - 6 = 20, where x is the temperature in degrees Farhenheit 6 hours ago. 2 x = 20 + 6, 2 x = 26, x = 26 : 2, x = 13 degrees F. We can prove it: 13 * 2 - 6 = 26 - 6 = 20 degrees F ( the current temperature ) Answer: The temperature 6 hours ago was 13 degrees F.Hope this helps. Let me know if you need additional help!

Answer: this is good

Step-by-step explanation:2 x - 6 = 20, where x is the temperature in degrees Farhenheit 6 hours ago. 2 x = 20 + 6, 2 x = 26, x = 26 : 2, x = 13 degrees F. We can prove it: 13 * 2 - 6 = 26 - 6 = 20 degrees F ( the current temperature ) Answer: The degrees 6 hours ago was 13 degrees yes very good

area is 1 square centimeter:
square feet. The ratio of the area in the drawing to the actual
square feet.

Answers

Answer:

Step-by-step explanation:

Answer:

The ratio of the area in the drawing to the actual area is 1 square centimeter:4 square feet.

Step-by-step explanation:

Find the number of feet represented by 1 centimeter in the scale drawing.

1 cm

2 ft

1 centimeter in the drawing equals 2 feet on the actual floor.

Step 2:

Find the side length of the floor in the scale drawing.

The area of the square in the drawing is 64 square centimeters, so the side length must be 8 cm.

Step 3:

Find the side length of the actual floor represented by 8 cm in the scale model.

1 cm × 8

2 ft × 8

=

8 cm

16 ft

The side length of the actual floor is 16 ft.

Step 4:

Since the area of a square is the side length squared, the area of the actual floor is 256 square feet.

Step 5:

The ratio of the area in the drawing to the actual area is 64 square centimeters:256 square feet.

Simplify the ratio.

The ratio of the area in the drawing to the actual area is 1 square centimeter:4 square feet.

A home improvement store sold wind chimes for $30 each.A costumer signed up for a free membership card and recieved a 5% discount off the price.Sales tax of 5% was applied after the disscount.What was the final price of the windchime?Show your work.

Answers

5%=.05
$30 x .05 = $1.5
Take $1.5 off of the $30.
After discount, the price was $28.5.
Sales price needs to be added.
$28.5 x .05 = $1.4
$28.5 + $1.4 = $29.9
$29.9 is the final price of the  wind chime.

Answer: 29.9

How to solve this problem

5%=.05

$30 x .05 = $1.5

Take $1.5 off of the $30.

After discount, the price was $28.5. Sales price needs to be added.

$28.5 x .05 = $1.4
$28.5 + $1.4 = $29.9

$29.9 is the final price of the wind chime.
