Answer:

<em>The correct option is:  C)  4x(3y + 7z)</em>

Step-by-step explanation:

Given expression is:   12xy+28xz

First we need to find the GCF(Greatest common factor) of 12xy and 28xz and then we will factor out that GCF.

12xy \Rightarrow 2\times 2\times 3\times x\times y\\ \\ 28xz\Rightarrow 2\times 2\times 7\times x\times z

We can see that the common factors are:  2,2, x

So, the GCF will be:  2\times 2\times x= 4x

Now factoring out 4x from the given expression, we will get.....

12xy+28xz\\ \\ = 4x(\frac{12xy}{4x}+ \frac{28xz}{4x}) \\ \\ =4x(3y+7z)

So, the complete factorization will be:  4x(3y+7z)

ILL GIVE BRAINLEST Determine whether the two angles in each figure are complementary, supplementary, or neither
Naily [24]
The first two angles are both complementary angles since they add up to 90*
I can’t see the last angle too well I think it’s a supplementary angle since it has a straight line meaning it should equal 180*

antiseptic1488 [7]

Answer:

there is no solution

Step-by-step explanation:

y + 7 = 3x

6x - 2y = 6    which can be simplied to be 3x - y = 6  (divide by 2)

let y = 3x - 7

substitute:  3x -(3x - 7) = 6

                  3x - 3x + 7 = 6

                              7 ≠ 6  therefore, no solution
