(Scroll to the bottom to see my answer) The order of operations is PEMDAS aka Parentheses. Exponents. Multiplication or Division (Which ever come first). Addition or Subtraction (again whichever comes first). Start with (12-9)=3 then multiply 3 by 3, three times=9 then multiply 2 and 7 together=14 then do 9-14=-5

So my final answer is -5! I might be wrong but I did my best! I hope I’m not too late!

50.24 centimeters squared

Step-by-step explanation:

The diameter (d) is 8 which means the radius is 4 (8/2)

27. Write down the co-ordinates of the points where the line y = 4x - 3 cuts the x-axis <br>​
Tamiku [17]

Step-by-step explanation:

it is a line, so that is 1 point, where it cuts the x-axis.

in general that means y = 0.

so,

0 = 4x - 3

4x = 3

x = 3/4

the point, where the line cuts the x-axis is

(3/4, 0)

Find the value of 2^-3*3^-2
Sergeeva-Olga [200]

2^{-3}\cdot 3^{-2}

2^-3=\frac{1}{2^3}

3^-2=\frac{1}{3^2}

\frac{1}{2^3}*\frac{1}{3^2}

\frac{1*1}{2^3*3^2}

2^3*3^2=72

=\frac{1}{72}

Hope this helps!

Thanks!

Really need need help on this please
Alexxx [7]

Answer:

\frac{7}{2}

Step-by-step explanation:

\frac{12-3y}{2} + y (\frac{2y-4}{y})

we substitute the value of "y" in the equation:

\frac{12-3(3)}{2} + 3 (\frac{2(3)-4}{3})\\\\\frac{12-9}{2} + 3 (\frac{6-4}{3})\\\\\frac{3}{2} + 3 (\frac{2}{3})\\\\\frac{3}{2} + 2\\\\\frac{7}{2}
