8 0

$a,b,c-\ sides\ of\ triangle\\\\a+b+c=18\ inches\\\\a=8inch\\\\\frac{b}{c}=\frac{2}{3}\\\\3b=2c\ \ --->b=\frac{2c}{3}\\\\8+\frac{2c}{3}+c=18\ |*3\\\\24+2c+3c=54\\\\5c=54-24\\\\5c=30\\\\c=\frac{30}{5}=6\\\\Length\ of\ shorter\ side\ is\ equal\ to\ 6\ inches.$

What is the answer to the equation X=3-(3x6)+2?

dolphi86 [110]

x = 3 - (3×6) + 2. We perform the operation in the bracket first.

x = 3 - 18 + 2

x = -15 + 2 = 2 -15 = -13

x = -13
