The perimeter of a triangle is 24 cm and the lengths of the sides
are in the ratio 3:4:5. Find the lengths of the three sides.

6, 8 and 10 cm

Step-by-step explanation:

Sum the [arts of the ratio, 3 + 4 + 5 = 12 parts

Divide the perimeter by 12 to find the value of one part of the ratio.

24 ÷ 12 = 2 cm ← value of 1 part of the ratio, thus

3 parts = 3 × 2 = 6 cm

4 parts = 4 × 2 = 8 cm

5 parts = 5 × 2 = 10 cm

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
