Use the order of operations to evaluate this expression: 7 + (5 – 9)2 + 3(16 ÷ 8).
Jet001 [13]

Remember to use PEMDAS when solving.

= 7 + (-4)2 + 3(2)

= 7 + (-8) + 6

= -1 + 6

= 5

Evaluate: \frac{23}{56} + \frac{3}{8} - ( - \frac{4}{28} )
MrMuchimi
I think this is what you mean. I don't know why the Latex didn't work. Good for you that you can use it.

\frac{23}{56} +  \frac{3}{8} - \frac{-4}{28}
\frac{23}{56} + \frac{3}{8} - \frac{-4}{28} Reduce the 4/28 to 1/7
\frac{23}{56} + \frac{3}{8} - \frac{-1}{7} Make the 2 minuses into a +
\frac{23}{56} + \frac{3}{8} + \frac{1}{7} 56 is the common denominator.
\frac{23}{56} + \frac{21}{56} + \frac{8}{56}

Answer = [23 + 21 + 8] / 56 = 52 / 56 = 13 / 14 When both numerator and denominator are divided by 4

13 / 14 <<<< answer.

\lim_{x \to 2^-} x^3=2^3=\boxed8\\  \lim_{x \to 2^+} 3x-4=3\cdot 2-4=6-4=\boxed2
