Write the steps for how to use a number line to multiply a 2 digit number by 20

1 answer:

4 0

(Pretend you're multiplying 15×20)
1. Start at 0 (obviously)
2. Go 20 numbers to the left and stop (if you're drawing or writing on the number line, make a line vertically to show that's where you stopped for the first 20
3. Do this 14 more times and keep on going to the right

Answer:

-3x-3y-z=38

Step-by-step explanation:

To find the equation of the tangent plane you can use

$\bigtriangledown f_x(x_0,y_0,z_0)(x-x_0)+\bigtriangledown f_y(x_0,y_0,z_0)(y-y_0)+\bigtriangledown f_z(x_0,y_0,z_0)(z-z_0)=0$

the point P is (-6,-6,-2). Hence you have

$(-6)(x-(-6))+(-6)(y-(-6))+(-2)(z-(-2))=0\\-6x-36-6y-36-2z-4=0\\-6x-6y-2z=76\\-3x-3y-z=38$

hope this helps!!

Factor 64b-16c to identify the equivalent expressions. *

scoray [572]

Answer:

The factored form of this would be 16(4b - c)

Step-by-step explanation:

In order to find this, look for the greatest common factor of 16 and 64. You can do this by listing out their factors. Once this is done and we identify 16 as the GCF, we can then put that on the outside of the parenthesis and divide all the terms inside by that number.
