Hi there!

Okay so remember PEMDAS. Also you could use a calculator for this but you can also use pencil and paper. Anyway, steps are below:

3²+(6-2)(4)-6/3

= 9+(6-2)(4)-6/3
= 9+(4)(4)-6/3
= 9+16-6/3
= 25-6/3
= 25-2
= 23

Your final answer is B, 23.

Hope this helped!

Which of the following equations is equivalent to s=πr^2h

suter [353]

Answer:

h = s / π.r²

Step-by-step explanation:

the given equation is s = π.r².h

Now if we have to calculate the value of h from the given formula then we will solve it so that h remains alone on one side of the equation.

This only possible when we divide term on both the sides by π.r²

s/π.r² = π.r².h/π.r²

h = s / π.r²

Therefore h = s / π.r² is the right option.

5 more than 3 times a variable, x, is 23

Monica [59]

3x + 5 = 23

5 more than(addition) 3 times(multiplication) a variable(x) is(equals) 23

(you add 5 to 3x)

If you need to solve for "x", you need to isolate/get the variable "x" by itself in the equation:

3x + 5 = 23 Subtract 5 on both sides

3x + 5 - 5 = 23 - 5

3x = 18 Divide 3 on both sides to get "x" by itself

$\frac{3x}{3} =\frac{18}{3}$

x = 6
