Terms they are examples of terms.

Answer:

2a, 3b and -4c are examples of terms.

Step-by-step explanation:

Given : Expression

To find : 2a, 3b and -4c are examples of ?

Solution :

We have given the expression

A term is made up of a constant multiplied by a variable.

In the given expression,

Variables are a, b and c.

Constant are 2,3 and -4.

So, 2a, 3b and -4c will make a term.

Therefore, 2a, 3b and -4c are examples of terms.

What is true about ABC? Check all that apply.

Ira Lisetskai [31]

In the given triangle , Coordinates of A (-1,3) , B (-5,-1), C (3,-1).

Let's find the slope of AB and AC .

Formula of slope is

$m = \frac{y_{2} - y_{1} }{x_{2} - x_{1}}$

For AB, slope is,

$m = \frac{-1-3}{-5+1} = \frac{-4}{-4} =1$

And slope of AC is

$\frac{-1-3}{3+1} = \frac{-4}{4} = -1$

Product of the slopes of AB and AC is

$= 1* (-1) =-1$

Since the product of the two slopes is -1, so AB and AC are perpendicular.

And if they are perpendicular, angle BAC is 90 degree, so the triangle is right triangle .

Now we check the length of the sides of the triangle, and for that we use distance formula , which is

$d = \sqrt{ (x_{2} - x_{1} )^2 + (y_{2} - y_{1} )^2}$

So for AB,

$AB = \sqrt{ (-3-1)^2 + (-5+1)^2} = \sqrt{32} = 4 \sqrt 2$

For AC,

$AC = \sqrt{ (-1-3)^2 + (3+1)^2 } =\sqrt{32} = 4 \sqrt 2$

For BC,

$\sqrt{(-1+1)^2 + (3+5)^2 } = 8$

And since two sides are equal, so the triangle is isosceles triangle .

A rectangular garden has an area of 154 square feet. If its width is 11 feet, what is its length?

kakasveta [241]

Answer:

$Width = 14feet$

Step-by-step explanation:

Given

$Area = 154$

$Width = 11$

Required

The length

Area is calculated as:

$Area = Length * Width$

Make Width, the subject

$Width = \frac{Area}{Length}$

So, we have:

$Width = \frac{154}{11}$

$Width = 14feet$

Polygon y is a scaled copy of polygon x using a scal factor of 1/3. Polygon y area is what fraction of polygon x area

Ksenya-84 [330]

9514 1404 393

Answer:

1/9

Step-by-step explanation:

The ratio of areas is the square of the scale factor for linear dimensions.

Area(y)/Area(x) = (1/3)^2 = 1/9
