Which is a factor of both terms of the expression 6f−12?


Answers

Answer:

6(f-2)

Step-by-step explanation:

Answer:

Step-by-step explanation:

If you solve the highest common  factor first, then you can look for other factors.

Solution

6 = 2 * 3

12 = 2*2*3

The highest common factor is one 2 and one 3 making 6.

Use the distributive property to show what the 2 factors look like when the common factor is taken out.

6( f - 2)

Other factors.

You could take out just 1 factor like 2 or 3

2(3f - 6)

3(2f - 4)

I would submit 6(f - 2)

Answers

The area of the rectangle and triangle are 48 mm² and 24 mm² respectively.

What is an area?

The area is the amount of space occupied by a two dimensional shape or object.

Area of rectangle = length * width = 6 mm * 8 mm = 48 mm²

Area of triangle = (1/2) * base * height = 0.5 * 6 * 8 = 24 mm²

What is 8 1/3 - 3 1/2?

Answers

29/6 = 4 5/6 simplified

Answer:

4 5/6

Step-by-step explanation:

Turn both 8 1/3 and 3 1/2 into improper fractions (just to make it less complicated).

8 1/3 = 25/3

3 1/2 = 7/2

Then, try and make the denominators the same by finding the LCD (least common denominator).

The least common denominator of 3 and 2 is 6. Multiply both the denominators (3 and 2) to get 6, multiply the numerator with it as well (I can't explain this part properly, but the fractions will somehow explain).

[tex]\frac{25*2}{3*2}[/tex] = [tex]\frac{50}{6}[/tex]

[tex]\frac{7*3}{2*3}[/tex] = [tex]\frac{21}{6}[/tex]

So, then subtract (50/6 - 21/6).

50/6 - 21/6

= 29/6 = 4 5/6

So, 8 1/3 - 3 1/2 is 4 5/6.

Find the surface area. HELP PLEASE!!!!​

Answers

Answer:

I think the answer is 792

Answer:

SA = 696cm^2

Step-by-step explanation:

First we need to identify the shapes

There are 3 rectangles and 2 triangles

Now the individual surface area for each shape

20 x 10 = 200 (1 rectangle)

1/2(12 x 8) = 48 (1 triangle)

Now we add them together

(200 x 3) + (48 x 2) = 696

Find the area of this circle. Use 3.14 for a 11 ft The area of the circle is about ft2. (Round to the nearest hundredth as needed.)​

Answers

Answer:

Area of circle is 379.94 feet²

Step-by-step explanation:

Given:

Radius of circle = 11 feet

To Find:

Area of circle.

Solution:

Here given that radius of circle is 11 feet. Using the formula of area of circle we will get the required area of circle

Area of circle = πr²

On substituting the required values:

Area = 3.14 × (11)²

Area = 3.14 × 121

Area = 379.94 feet²

Hence,

Area of circle is 379.94 feet²

Group of answer choices

A.$8.20

B.$7.20

C.$4.20

Answers

The answer would be D.
2.80+2.80=5.6
10-5.6=$4.40

One pound of nuts cost $2.80 -> 2 pounds cost $2.80 x 2 = $5.60

We can find the amount of change he got : $10.00 - $5.60 = $4.40

Yvette paid $921 for tires for her car. She got special financing with a 0% interest rate if she paid off the tires in 6 months. How much will she have to pay each month in order to pay off the tires before she will have to pay interest?
a
$183.50
b
$153.50
c
$76.75
d
$92.10

Answers

Answer: B

Step-by-step explanation:

In 6 months she will have to pay $921

In 1 month she has to pay [tex]\frac{921}{6}[/tex] = $153.50

Each month, Yvette has to pay $153.50 in order to pay off the tires before she will have to pay interest

Therefore, B is the correct answer

You’re answer is B . $153.50 dollars a month because $921 divided by 6 months is $153.50 and there’s 0% interest rate so it don’t change the problem at all it’s still going to be B . $153.50

X - y = -2 7x + 2y = -5

Élimination method

Answers

Answer:

x = -1, y = 1

Step-by-step explanation:

Multiply the top equation by 2:

[tex]2x - 2y = - 4[/tex]

Leaving the bottom equation unchanged, add the two resulting equations to eliminate y, obtaining:

[tex]9x = - 9[/tex]

Solve this for x, and then substitute this value of x into the bottom equation. Finally, solve for y.

[tex]x = - 1[/tex]

[tex]7( - 1) + 2y = - 5[/tex]

[tex] - 7 + 2y = - 5[/tex]

[tex]2y = 2[/tex]

[tex]y = 1[/tex]
