First, you need to find the greatest common factor, and because we are factoring out the minus sign, it should be a negative number.

For -1 & 30, the GCM is -1, and using the GCM, we can factor each of them out:
-1 30
/ \ / \
-1 x 1 -1 x 30

Then, we can use distributive property to factor out the minus with the GCM outside of the parentheses:

-1 + 30 =

-1(1 + 30)

Answer:

8cm

Step-by-step explanation:

x is similar to the side 12cm.

We know the second triangle is rotated counter-clockwise from the first because similar triangles have the same angle measurements.

Since the angle in the first triangle between 9cm and 15cm is 53°, it can't be similar to the angle between x and the hypotenuse in the second triangle.

Find the scale factor:

Triangle 1/Triangle 2

Divide two similar sides.

6/9 = 2/3

Multiply the scale factor by the similar side to find x.

x = 12*(2/3)

x = 8

creativ13 [48]

Answer:

Step-by-step explanation:

common ratio=18/-3=-108/18=-6, a=-3

sn=a(r^n-1)(r-1)

sn=-3((-6)^n-1)(-6-1)

sn=-3(-6)^8-1)/(-7)

s8=-3(1679615)/(-7)

s8=719836

Write an inequality for the sentence: twice a number, decreased by the quotient of that number and 2, is at least 12
Rudiy27
For the answer to the question above,  If you've noticed, the statement mentioned "a number". Let's assign x to be the number. The first statement is twice a number (2x). Then, decreased by the quotient of that number and 2 (-x/2). Lastly, the statement at least 12 is written as >12. 
So the answer is
2x - (x/2) >12
