An isosceles triangle has AT LEAST 2 equal length sides.
5 + 4 - 1 = 7
7 + 4 - 1 = 10
10 + 4 - 1 = 13
And so on
x=3 and x= -2
Step-by-step explanation:
we could simplify it to x*2 + x -6 = 0
then 2 numbers whose sum is 1 and product is -6
the numbers are 3 and -2
30 × 5 = 150
150 - 110 = 40
40 ÷ 2 = 20
So 20 kids brought their own lunch
Hope this helped. Have a great day!
