"The perimeter of a triangle is 294cm. The sides are x + 2, 2x + 3, and 3x + 1. Find the length of each side of the triangle."

50cm, 99cm, 145cm

Step-by-step explanation:

The perimeter is just the distance around the triangle. We have all three sides.

So

(x+2) + (2x + 3) + (3x + 1) = 294

Combine like terms

6x + 6 = 294

Subtract 6 on both sides

6x = 288

Divide 6 on both sides

x = 48

So the sides are

x + 2 = 48 + 2 = 50 cm

2x + 3 = 2(48) + 3 = 96 + 3 = 99 cm

3x + 1 = 3(48) + 1  = 145 cm

Checking, first:

50 + 99 + 145 = 194 cm

Plug in x = 48 to the original equation.

48 + 2 + 2(48) + 3 + 3(48) + 1 = 294

48 + 2 + 96 + 3 + 144 + 1 = 294

294 = 294

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
