Answer:

9.

Step-by-step explanation:

Factors of 27: 1, 3, 9, 27

Factors of 45: 1, 3, 5, 9, 15, 45.

The GCF (Greatest Common Factor) of 27 and 45 is <u>NOT</u> 1, 3, or 27 because 27 is not a factor of 45, and since we are trying to figure out the <u>GREATEST</u> common factor, one and three do not work either. If you need more help, feel free to ask! I am on Brainly from 1 - 2 pm. EST, so if you have any further questions about this subject or my answer, feel free to ask me!

Find all real solutions of the equation. (if there is no real solution, enter no real solution.) 35x2 12x − 36
solmaris [256]
Important:  35x2 12x − 36 is not an equation; to obtain an equation, you must set <span>35x2 12x − 36 = to 0:

</span><span>35x^2 + 12x − 36 = 0.  Also, "the square of x" must be represented by "x^2," and you must insert either the + or the - sign in front of the term 12x.

I am assuming that you meant   </span>35x^2 + 12x − 36 = 0.

If that is indeed the case, then a = 35, b = 12 and c = -36

and the discriminant is b^2 - 4ac, or (12)^2 - 4(35)(-36) = 5184.

Since the discriminant is positive, this equation has 2 real, unequal solutions.  They are
        -12 plus or minus sqrt(5184)
x = -----------------------------------------
                         2(35)

What is the surface area of the rectangular prism below?
Andrew [12]

Answer:

B ( 432 units^2)

Step-by-step explanation:

Total surface area= 2*(6*6)+ 4*(15*6)

There are 2 squares at each end of the same size so total area will be 2*(6*6)

If we look at the rectangles( bottom, top and the sides), we can see that all are of same dimensions and there are 4 of them so it's 4*(15*6)

In short, total surface area= 2*(6*6)+ 4*(15*6) = 432 units^2

The surface area of a cube is 600 square inches. What is the area of one of its faces? A. 6 square inches B. 36 square inches C.
erastovalidia [21]

check the picture below.


recall that a cube sides are all equal in length, and it's really just 6 squares stacked up to each other at the edges.


so if 600 is the total area of those 6 squares, then just for one is 600/6 in².
