What is the perimeter

Westkost [7]

Answer:

The answer to your question is: letter D

Step-by-step explanation:

First we need to find the distances between the points,

distance AB = 8 get it just by counting the points in the graph

distance AC = 9 get it just by counting the points in the graph

To know the distance BC, use the pythagorean theorem

c2 = a2 +b2

c2 = 8² + 9²

c² = 64 + 81

c² = 145

c = 12.04

Finally, perimeter = AB + AC + BC

= 8 + 9 + 12.04

= 29.04 units

Answer:

$\frac{5}{4} x - 2 = \frac{3}{2} x-4$

Step-by-step explanation:

$\frac{5}{2} x +\frac{7}{2} =\frac{3}{4} x+14 \\\frac{5}{2}x -\frac{3}{4} x=14-\frac{7}{2} \\\frac{10-3}{4} x =\frac{28-7}{2} \\\frac{7}{4} x =\frac{21}{2} \\x = \frac{21}{2} * \frac{4}{7} = 6 \\$

$\frac{5}{4} x -9 = \frac{3}{2} x-12 \\\frac{5}{4} x - \frac{3}{2} x= -12 + 9 \\\frac{5-6}{4} x = -3 \\\frac{-1}{4} x = -3 \\x = -3 * -4 \\x = 12$

$\frac{5}{4} x-2=\frac{3}{2} x-4 \\\frac{5}{4} x-\frac{3}{2} x=-4+2 \\\frac{5-6}{4}x=-2 \\\frac{-1}{4} x = -2 \\x = -2 * -4 \\x = 8$

$\frac{5}{2} x -7 = \frac{3}{4} x+14 \\\frac{5}{2}x -\frac{3}{4} x=14+7 \\\frac{10-3}{4} x =21 \\\frac{7}{4} x =21 \\x = 21 * \frac{4}{7} = 12 \\$

You could also replace x for 8 in every equation and see if both sides give the same answer

Can somebody please help my with this question

Answer:

All the possible values of $a-b$ lies in the interval $3$ .

Step-by-step explanation:

As the range of $a$ is

$3$

As the range of $b$ is

$4$

As $a$ contains the set of number between 3 to 4, and $b$ contains the values of from 4 to 5.

$a-b$ can be obtained by subtracting the values of $b$ from $a$ .

So,

$a-b$

⇒ $(3$

⇒ $3$

Therefore, all the possible values of $a-b$ lies in the interval $3$ .
