Two sides of a triangle have the same length. the third side measures 2 m less than twice the common length. the perimeter of the triangle is 22 m. what are the
lengths of the three sides?
what is the length of the two sides that have the same length?

Step-by-step explanation:

first side: x

second side: x

third side: x+x-2 = 2x-2

perimeter (sum of the sides): 22.

therefore

x+x+2x-2=22

4x-2=22

4x=24 /:4

x=6 [m]

so:

1st side: x=6m

2nd side: x=6m

3rd side: 2x-2=2*6-2=10m.

these sides have 6m, 6m, 10m length.

answer: a.   one is a factor of every whole number since every number is divisible by itself.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
