Triangle with sides of 8.2cm,3.9cm, and 4.5cm. what is the perimeter?

Perimeter is the measurement all around the shape. So, to do this we wolud need to add this measurments together

Step-by-step explanation:

8.2+3.9=12.1

12.1+4.5=16.6

16.6cm

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
