What is the greatest common factor or 12a and 9a^2

1 answer:

8 0

The factors of 9 are 1, 3 and 9.
The factors of 12 are 1, 2, 3, 4, 6 and 12.
The factor of a and a^2 is just "a."

For coefficients, the common factors of 9 and 12 are 1 and 3 only. But the greatest common factor is 3.
For variables, the greatest factor is just also "a."

Multiplying these two factors, we get the answer: 3a

Please help calculate the total surface area. Thanks

Gnoma [55]

Answer: 70cm³

EXPLANATION:

1/2 x base x height x 2 (this is to find the surface area of one of the triangular faces since the other side of the triangular shape has the same measurements you should multiply it by 2 straight away since it makes it easier for you)

1/2 x base x height x 2

1/2 x 3 x 3 x 2 ← (to get the height of the triangle substract 7 from 10)

1/2 x 18 ← (multiply 3x3x2=18)

9cm³ ←(since 18 is 2x9 your answer is 9cm³)

1/2 x base x height x 2 (this is to find the surface area of the other triangular face with different measurements and since the other side of the triangular shape has the same measurements you should multiply it by 2 straight away since it makes it easier for you)

1/2 x base x height x 2

1/2 x 4 x 3 x 2 ← (to get the height of the triangle substract 7 from 10)

1/2 x 24 ← (multiply 4x3x2=24)

12cm³ ←(since 24 is 2x12 so your answer is 12cm³)

Then next you have to find the surface area of one face of the rectangle and multiply it by 2 since the back side of the rectangle has the exact same measurements. The formula to find the area of a rectangle is area= length x breath

A= 3x7= 21cm³

then find the area of the other rectangular face with different measurements and multiply it by 2 since the back side of the rectangle has the exact same measurements. The formula to find the area of a rectangle is area= length x breath

A= 4x7= 28cm³

FINALLY

add all the areas of the faces you have found and you'll get the total surface area!

9+12+21+28=70cm³

Thank you! I hope you understood something and I hope you have a great day! good luck!

stacey made 8 necklaces in 48 minutes. nick made 4 necklaces in 24 minutes. is the rate at which they made necklaces equivalent.

Bingel [31]

Answer:

Yes.

Step-by-step explanation:

Divide - 48 / 8 which equals 6. Stacey makes 6 necklaces in 1 minute. Then, do 24 / 4. This also equals 6. Nick makes 6 necklaces in one minute. Therefore, their speed is equivalent.

Tyrone claims that the first step to simplify this expression

ser-zykov [4K]

Answer:

1/(m^4*n^2

Step-by-step explanation:

The given expression is

(m^2*n^-3)/(m^6*n^-1)

Tyrone's approach.

Raising the expression to the 3rd power will not help. It will make the expression more complicated.

Alisha's approach.

(m^2*n^-2)/(m^6*n^-1)

= m^(2-6)*n^(-3+1)

= m^-4*n^-2

= 1/(m^4*n^2)

Alisha's approach will simplify the expression to 1/(m^4*n^2
