Answer:

It would be Choice A, x = 7

Step-by-step explanation:

So with this, it wants for you to factor out x^2-8x+7.

Since we already have one of the factors, (x-1), this removes most of the work with it. The task is to find the second factor.

With this, the FOIL method is needed. First, Outer, Inner, and Last of each factor are multiplied. Note that the ending numbers of the factor should multiply to give the final number of the standard form. Also, the middle value of the standard form should be the addition of each of the numbers * the x value.

Choice A:

x^2 – 8x + 7

(x-1)(x-7)

Choice A is correct as it follows the rules given above.

Choice B:

x^2 – 8x + 7

(x-1)(x+7)

Choice B is incorrect, because it would be x^2+6x-7 if FOIL is done.

Choice C:

x^2 – 8x + 7

(x-1)(x+8)

Choice C is incorrect, because it would be x^2+7x-8 if FOIL is done.

Use a division ladder to find the GCF of 34 and 60. A4 B3 C1 D2
Sloan [31]

Answer:

D.2


Step-by-step explanation:

First, you need to divide 34 and 60 by A.4, when you divide that you see that 4 dose not go in to 34 evenly and go"s in to 60 evenly, so this is incorect.


Now we will divide 34 and 60 by B.3, when you divide, you see that 3 dose not go into 34 evenly and go"s in to 60 evenly, so this is also incorect.


Then we divide 34 and 60 by C.1, when we divide this one you find that 1 go"s in to 34 evenly and 60 evenly, so this is a posible answer.


finally we divide 34 and 60 by D.2, when we do this we find that 2 go"s in to 34 evenly and 60 evenly, so this is also a posible answer.


All though C. and D. both go in to 34 evenly and 60 evenly, we are looking for the GCF (Greatest Common Factor). So the biggest number of C.1 and D.2, is D.2


So the answer is D.2.


Hoped this helped, Have a grate day!

Q2.
Nimfa-mama [501]

Answer:

see below

Step-by-step explanation:

A = {8, 9, 10, 11, 12, 13, 14} and   B = {2, 4, 6, 8, 10, 12, 14, 16, 18}

----------------

(i) List down the elements of A’ and B’

{8, 9, 10, 11, 12, 13, 14, 2, 4, 6, 8, 10, 12, 14, 16, 18} - this is the elements of both sets

----------

(ii) Are sets A - B and B - A equal sets?

A-B= {9, 11, 13}

B-A= {2, 4, 6, 16, 18}

These are not equal as we can see

----------

(iii) Find and compare the sets (AUB)’ and A’∩B’ and share your observations

A∪B= {2, 4, 6, 8, 9, 10, 11, 12, 13, 14, 16, 18}- union included all elements of both sets

A∩B= {8, 10, 12, 14} - intersection only includes common elements
