The gcf of 135 225 270

Answers

The greatest common factor of 135 225 and 270 is 135/225 = 3/5

hope you found this helpful ;)

The GCF of 135, 225, and 270 is 45.

The GCF (Greatest Common Factor) is the largest number that divides evenly into two or more numbers. To find the GCF of 135, 225, and 270, we need to find the common factors of the three numbers and choose the largest one.

The factors of 135 are: 1, 3, 5, 9, 15, 27, 45, 135.

The factors of 225 are: 1, 3, 5, 9, 15, 25, 45, 75, 225.

The factors of 270 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270.

The common factors of 135, 225, and 270 are: 1, 3, 5, 9, 15, 45.

The largest common factor is 45. So, the GCF of 135, 225, and 270 is 45.

What's the simplified form of 2x + 3 - x + 5?a. 3x + 8
b. x - 8
c. x - 2
d. x + 8

Answers

D.
Because you can combine all like terms. 2x and -x can be solved. That would equal x. +3 and +5 can be combined to make a positive 8. Therefore the answer would be x+8.

Ok so at first this problem may seem confusing but no worries. MATH is like that so our first step is to combine like terms which are the variables in the equation . So we have 2x+3-x+5 so like I said combine like terms is the first step so 2x and 1x are like terms because they have the variable x involved so when we subtract we get a result of 1x now wr have to add the constants which afr the numbers without variables which would equal the final form 1x+8 your answer is d
