To do this follow the rule of PEMDAS:

Parenthesis, exponents, multiplication, division, addition, and subtraction.

First, complete the work inside the parenthesis:

(2 x 6) = 12 (3 x 4) = 12

Now your equation should look like this:

12 x 12

The next step in the rule of PEMDAS is exponents. There are no exponents in this equation so skip over that. Now we move onto multiplication.

Now finish the equation by multiplying the 12's together like so:

12 x 12 = 144

Then ignore the rest of the PEMDAS rule since you have already completed the equation.

Hope this helps you and you can use it for future reference. ^w^

Hey!
So you have a net of the figure. It's broken into several 2D shapes. What you an do it find the area of each shape and add it together.
Triangles:
A = (b*h)/2
A= (5 * 3) / 2
A = 15/2
same thing for the second one
15/2 * 2 = 15
Don't forget, there are 2 triangles so it's really 15 for both

Rectangles:
A=b*h
A= 7*5
A=35

A=7*5
A=35

A=3*7
A=21

35+35+21=91

Now add the sum of the area of the triangles and the sum of the area of the rectangles

91+15 = 106

106 is the surface area
Hope this helps!

For the function P(x) = x3 − 9x, at the point (2, −10), find the following. (a) the slope of the tangent to the curve (b) the in

Shalnov [3]

Answer:

3, in both a), b)

Step-by-step explanation:

a) The slope of the line tangent to the curve that passes through the point (2,-10) is equal to the derivative of p at x=2.

Using differentiation rules (power rule and sum rule), the derivative of p(x) for any x is $p'(x)=3x^2-9$ . In particular, the value we are looking for is $p'(2)=3(2^2)-9=12-9=3$ .

If you would like to compute the equation of the tangent line, we can use the point-slope equation to get $y=3(x-2)-10=3x-16$

b) The instantaneus rate of change is also equal to the derivative of P at the point x=2, that is, P'(2). This is equal to $p'(2)=3$ .
