Answer:

It's a right triangle.

Step-by-step explanation:

I solve kinda a bit but its hard (Algebra 2)

melisa1 [442]

Answer:

x=9

Step-by-step explanation:

The goal is to combine our knowledge of geometry area and algebra skills to solve this problems.

We know area of rectangle is

$l \times w$

where l is the length and w is the width. We know that one side is 3 less than the other side. We can use L or W but let use L. Let x replace L

One side is x, while the other side is

$x - 3$

Both multiply to 54.

$x(x - 3) = 54$

${x}^{2} - 3x = 54$

${x}^{2} - 3x - 54 = 0$

$(x - 9)(x + 6)$

$x = 9$

or

$x = - 6$

Distance. is positive so x=9

Write in standard form: An equation of a line which has a slope of 2/3 and contains the point (0,2)

Rina8888 [55]

The equation of a line with slope 2/3 and point (0,2) is 3y - 2x = 6

The equation of a line is given as

$y = mx + c$

m = slope

c = intercept

The data given are

slope (m) = 2/3
x = 0
y = 2

<h3>Intercept</h3>

Put in the values into the equation above and solve for the intercept.

$y = mx + c\\2 = 2/3(0) + c\\c = 2$

<h3>Equation of the line</h3>

$y = 2/3x +2\\$

Multiply through by 3

$y = 2/3(x) +2\\y(3) = (3)2/3x + 2(3)\\3y = 2x + 6\\3y - 2x = 6$

From the above calculation, the equation of a line is 3y - 2x = 6

Alexandra is two years older than brad. cecilia is three years younger than alexandra. all three ages added together gives a tot

MatroZZZ [7]

Let us say that:

x = age of brad

x + 2 = age of Alexandra

(x + 2) – 3 = age of Cecilia = x – 1

We are also given that:

x + x + 2 + x – 1 = 37

<span>
solving for x:</span>

3x + 1 = 37

3x = 36

x = 12 = age of brad

x + 2 = 14 = age of Alexandra

<span>x – 1 = 11 = age of cecilia</span>

Which statement about the net is true?

Schach [20]

The net cannot be folded to form a pyramid because the faces that are not a base are not all triangles

If you fold this net up, you will get a triangular prism, NOT A PYRAMID.

A pyramid can have ANY polygon as its base, as long as all the other rest of the shapes are triangles.

Depending on the base, the number of triangles in a net of a pyramid must match the number of sides its particular base has.

For example, if you have a square pyramid turned into a net:
The base is a square (4 sides)
There should be 4 triangles on each side.

Because a pyramid is where all the triangles must meet up at a point.

Hope this helps!

In 2000, an estimated 7.7 x 10^7 spoke French as their first language and an estimated 1 x 10^8 people spoke German as their fir

saw5 [17]

Answer:

German

Step-by-step explanation:

Given :

Number of people who spoke French as first language in 2000 = 7.7 * 10^7 ; in standard form ;

7.7 * 10^7 = 7.7 * (10 * 10* 10 * 10* 10* 10 * 10) = 77,000,000 = 77 million

Number of people who spoke German as first language in 2000 = 1 * 10^8 ; in standard form ;

1 * 10^8 = 1 * (10 * 10* 10 * 10* 10* 10 * 10 * 10) = 100,000,000 = 100 million

German had more speakers
