Answer: 12
Step-by-step explanation:
So if its 1-10, and you can either roll a 1 or 2, it would be 2/10, then simplified to 1/5, and in order to get the answer you need to multiply it by 60
1/5 x 60/1 = 12
(sorry if I got it wrong, feel free to correct me if I did)
Hope this helps u out :D
Answer:
The GCF is 3w
Step-by-step explanation:
You have to find the GCF of
6w^3, 3w^2, 9w
You can start with 3. Then get:
6w^3/3 = 2w^3
3w^2/3 = w^2
9w/3 = 3w
The following factor is w. It has to have an exponent of one, as it the smallest exponent present in the 3 numbers:
2w^3/w = 2w
w^2/w = w
3w/w = 3
Expression:
6w^3 - 3w^2 - 9w= 3w(2w^2 - w - 3)
The GCF is 3w.
Two triangles: left triangle with y degrees and 40 degrees and right triangle with x degrees.
- 40 degrees from the left triangle, when adding with the unknown angle of the right triangle, is equal to 180 degrees.
- Adding left triangle's (third) undetermined angle and x degrees angle (the other same angle), is equal to 90 degrees.
- The right triangle is an isosceles triangle, meaning two equal angles, and one of them is x degrees. Thus, the other same angle is also x degrees.
----------------------------------------------------------------------------------------------------------
1) Subtract 180 - 40 = 140 degrees. 140 degrees is the unknown angle of right triangle.
2) 140 + x + x = 180 (equation)
- 140 + 2x = 180
- 2x = 180 - 140
- 2x = 40
- x degrees = 20 degrees
ANSWER: x = 20 DEGREES
----------------------------------------------------------------------------------------------------------
1) With knowledge of x degrees being 20 degrees, the other same angle is 20 degrees, too.
2) Subtract 90 - 20 = 70 degrees. 70 degrees is the (third) undetermined angle
of left triangle.
2) 70 + 40 + y = 180
- 110 + y = 180
- y = 180 - 110
- y = 70 degrees
ANSWER: y = 70 DEGREES

The square root of 1444 is 38
(I used a calcultor)
The answer should be ( 2x + 6) (2x - 6) By proving through expansion:
