The sides of a traingle are in the ratio 3:4:5. what is the length of each sdie of the traingle is 30 cm
liraira [26]
X - the unit
3x; 4x; 5x - the lengths of the sides
3x + 4x + 5x = 30
12x = 30   |:12
x = 2.5
3x = 3 · 2.5 = 7.5 cm
4x = 4 · 2.5 = 10 cm
5x = 5 · 2.5 = 12.5 cm

____ [38]

Answer:

y > -5x + 3

Step-by-step explanation:

Answer:

y > –5x + 3

Step-by-step explanation:

we know that

1) The solution of the inequality is the shaded area above the dashed line

so

The linear inequality could be

y > –5x – 3

y > –5x + 3

y > –3x + 5

2) The slope of the dashed line is negative ----> the three options have slope negative

3) The y-intercept of the dashed line is (0,3)

therefore

The linear inequality is

y > –5x + 3

...............................................................................................................................................

Answer:

Step-by-step explanation:

To find the linear inequality , Let pick two points from the graph

Lets pick (0,3) and (1,-2)

Lets find out slope using the points

Slope m= -5

y intercept b= 3

Equation of the line is y=mx+b

Now we look at the shaded part. we use test point (0,0)

(0,0) is not in the shaded region

0 >3 is false

What expression represents the width of the rectangle
Oduvanchick [21]
<h3><u>Answer:</u></h3>

  • <u>x </u><u>-</u><u> </u><u>8</u>

<h3><u>Solution</u><u>:</u></h3>

We are given a rectangle with one of its sides ( length ) equal to ( x - 7 ) Meters.

  • Also we are given the area of the rectangle as x² - 15x + 56 square meters .

We have to find the expression for another side of the rectangle i.e it's width

We will use the formula of area of rectangle to find the expression :

  • <u>A</u><u>rea </u><u>=</u><u> </u><u>length </u><u>×</u><u> </u><u>width</u>

Therefore,

‎ㅤ‎ㅤ➝ A = l × w

‎ㅤ‎ㅤ➝ x² - 15x + 56 = ( x - 7 ) × w

‎ㅤ‎ㅤ➝ x² - 8x -7x + 56 = ( x - 7 ) × w

‎ㅤ‎ㅤ➝ (x² - 8x )( - 7x + 56 ) = ( x-7 ) w

‎ㅤ‎ㅤ➝ x( x - 8 )-7( x - 8 ) = ( x - 7 )w

‎ㅤ‎ㅤ➝ ( x - 8 )( x - 7 ) = ( x - 7 )

‎ㅤ‎ㅤ➝ ( x - 8 )w = ( x - 8 )( x - 7 )

‎ㅤ‎ㅤ➝ w = ( x - 8 )( x - 7 ) / ( x - 7 )

‎ㅤ‎ㅤ➝ <u>w = ( x - 8 )</u>
