Answer:

No

Step-by-step explanation:

Triangular Inequalities state that in a triangle, the sides must always be less than the sum of the other two.

You would have sides x, 2x, 3x in this case and use the inequality a+b>c.

if...

a=x, b=2x, c=3x

then...

x+2x>3x

3x>3x which is false.

Therefore you cannot make a triangle with sides proportional to 1, 2, and 3.

What is 12/21 divided by 3/14
sladkih [1.3K]
To do this problem, you gotta cross-multiply. SO, \frac{12}{21} multiplied by \frac{14}{3}

12 times 14 = 168
21 times 3 = 63
Then the final answer is \frac{168}{3}

What is the slope of a line parallel to the line whose equation is 5x+y=-9
Rzqust [24]

Answer:

slope = - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c (m is the slope and c the y- intercept )

Given

5x + y = - 9 ( subtract 5x from both sides )

y = - 5x - 9 ← in slope- intercept form

with slope m = - 5

Parallel lines have equal slopes, thus

The slope of a parallel line to the given equation is m = - 5
