Find the greatest common factor of 15x^2y^3 and -18x^3yz <br> The Answer has to be like _x_y_
Daniel [21]

Answer:

The greatest common factor of this would be 3x^2y

Step-by-step explanation:

In order to find this, first find the greatest common factor of the coefficients. Since 3 goes in evenly to both 15 and -18, then we know that it is a common factor.

From there we need to find the number of x's. Since the first term only has 2 x's and the second has 3, we take the lowest number. (x^2)

And since the first term has 3 y's and the second has just 1, we take the lowest number (y).

How do you measure the perimeter of a shape​
Advocard [28]

Perimeter is a measure of the area or distance around a two-dimensional shape. On a rectangle, for instance, the perimeter is the total length of the rectangle's outline, including the two widthwise borders and the two lengthwise borders.

<u><em> To determine the perimeter of a shape</em></u>, therefore, you add together all the dimensions that make up the shape's outer edge. Being able to find the perimeter of a shape has many applications in the real world. Say, for example, that you wanted to build a fence around your backyard. In order to purchase materials, you need to know how much fencing you'll need, and to determine that you have to figure out the perimeter of the area you want to fence in.

Which of the following is the surface area of the right cylinder below?
yarga [219]

Answer:

if it is TSA- 396 or 395.64

if it is CSA- 88 or 87.92

Step-by-step explanation:

r=7

h=2

TSA= 2 pi r(r+h)

=2*22/7*7*9= 396

<em>CSA</em>= 2 pi r h

2*22/7*7*2=88

when you use pi as 3.14 instead of 22/7 you get the answer with the decimal symbol.. in such case the TSA would be 395.64 and CSA would be 87.92
