Answer:

b = 45.9 - c

Step-by-step explanation:

A scalene triangle has non of its sides equal.

Perimeter = 54.6

side a = 8.7 cm

side b = unknown

side c = unknown

Perimeter of a shape is sum of all its sides.

Perimeter = a + b + c

54.6 = 8.7 + b + c

Making b the subject

b = 54.6 - 8.7 - c

b = 45.9 - c

The value of b is (45.9 - c)

Points (3,1) and (1,4) lie on line k. What is the slope of the line that is perpendicular to k?

denis-greek [22]

First we need to find the slope of line k. Using the slope formula, we fill in accordingly: $m= \frac{4-1}{1-3}$ . The slope is -3/2. The slope of a line that is perpendicular to line k will have the opposite sign (so, positive) and will be the reciprocal of the line k's slope (so, 2/3). You could also say, more "mathematically legal", that the product of the slopes of perpendicular lines is -1, but it's easier to just say that they are opposite reciprocals. The slope you're looking for is 2/3. Choice 3 above.
