Answer:

$6(2z + 3)$

Step-by-step explanation:

12 → 1, 2, 3, 4, 6, 12

18 → 1, 2, 3, 6, 9, 18

The GCF is 6

$12z + 18$

$6(2z + 3)$

Answer: $6(2z + 3)$

Answer: 6(2z + 3)

Step-by-step explanation:

So, with the distributive factor you want to find the greatest common factor. In this case, the greatest common factor is 6 because it can go into both 12 and 18. So now you need to simplify the numbers. You would put the 6 on the outside because it is the GFC.

Now, you need to divide both numbers by 6 and your equation should look like this:

6(2z +3)

Hope this helps! :)

Use the diagram and the value of x to find the measures of BCE and ECF.

stepan [7]

Answer:

125° and 55°

Step-by-step explanation:

∠ BCE and ∠ ECF are adjacent angles and are supplementary, thus

10x + 15 + 5x = 180, that is

15x + 15 = 180 ( subtract 15 from both sides )

15x = 165 ( divide both sides by 15 )

x = 11

Thus

∠ BCE = 10x + 15 = 10(11) + 15 = 110 + 15 = 125°

∠ ECF = 5x = 5(11) = 55°

What is the value of 6x - 3y if x = 5 and y= -1

nadezda [96]

Answer:

Step-by-step explanation:

6x - 3y

=> x = 5, y = -1 Substitute in the above equation,

=> 6(5) - 3(-1)

=> 6(5) + 3

=> 30 + 3

=> 33

1.) Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth .x squared minus 21 x equals n

Andrew [12]

Part 1
We are given $x^2-21x=-4x$ . This can be rewritten as $x^2-18x=0$ .
Therefore, a=1, b=-18, c=0.
Using the quadratic formula
$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}=\frac{-\left(-18\right)\pm \sqrt{\left(-18\right)^2-4\left(1\right)\left(0\right)}}{2\left(1\right)}$
$x=\frac{18\pm 18}{2}$

The values of x are
$x_1=\frac{18-18}{2}=0$
$x_2=\frac{18+18}{2}=18$

Part 2
Since the values of y change drastically for every equal interval of x, the function cannot be linear. Therefore, the kind of function that best suits the given pairs is a quadratic function.

Part 3.
The first equation is $y=x^2+2$ .
The second equation is $y=3x+20$ .

We have
$x^2+2=3x+20$
$x^2-3x-18=0$
Factoring, we have
$\left(x-6\right)\left(x+3\right)=0$
Equating both factors to zero.
$x_1-6=0\rightarrow x_1=6$
$x_2+3=0\rightarrow x_2=-3$

When the value of x is 6, the value of y is
$y=3\left(6\right)+20=38$

When the value of x is -3, the value of y is
$y=3\left(-3\right)+20=11$

Therefore, the solutions are (6,38) or (-3,11)
