The sides of a triangle have lengths x + 3, 4(x - 13), and 3 over 4 x. The perimeter of the triangle is 3x +6. What is the lengt

nignag [31]

Answer:

shortest side = 15

Step-by-step explanation:

The question is a bit ambiguous. Do you mean (3/4) x or do you mean 3/(4x)?

I'll take it to be the first one.

(x + 3) + 4(x - 13) + (3/4)x = 3x + 6 Remove the brackets on the left

x + 3 + 4x - 52 + 0.75 x = 3x + 6 Combine

5.75x - 49 = 3x + 6 Subtract 3x from both sides.

2.75x - 49 = 6 Add 49 to both sides

2.75x = 55 Divide by 2.75

x = 55/ 2.75

x = 20

Now for the shortest side

x + 3 = 23

4(x - 13) = 4(20 - 13) = 4*7 = 28

(3/4)*20 = 15

The shortest side = 15

Answer:

The equation of line in the form of Ax + By = C is: $\mathbf{4x+y=-17}$

Step-by-step explanation:

We need to find the equation of line, with the given slope passes through the given point.

Slope m = -4

Point: (-2,-9)

We need to find slope and y-intercept of the line.

The slope of line is given m = -4

Now, we need to find the y-intercept

Using the point (-2,-9) and slope m = -4, we can find y-intercept

The formula used will be: $y=mx-b$

Putting values of: y= -9, x =-2 and m = -4

$y=mx+b\\-9=-4(-2)+b\\-9=8+b\\b=-9-8\\b=-17$

So, y-intercept b = -17

Now, the equation of required line having slope m = -4 and y-intercept b = -17 is:

$y=mx+b\\y=-4x-17$

Writing equation in required form i.e. of Ax + By = C

$y=-4x-17\\4x+y=-17$

So, the equation of line in the form of Ax + By = C is: $\mathbf{4x+y=-17}$
