Only thing to do is simply by combining like terms and possibly some factoring

5q- 7a+ (2q) = 5q - 7a + 2q = 7q + 7a = 7(q+a)

What is your question exactly?

All you have is an expression and some function notation

x1/4+1-x1/6=1

x1/4 - x1/6= 0 subtract 1 from each side to isolate x

x(1/4 - 1/6) = 0 factor out the common factor ( the x ) again to isolate x

x(2/24) = 0 simplify the parenthesis

x(2/24) = 0 when x = 0 by the zero product property

All you have to do is

(x) + (x + 3) + (x + 5) = 20
3x + 8 = 20
3x = 12
x = 4

You have to add the side lengths together and then set them equal to the perimeter, then simplify from there.

Just expand the brackets
(4-3i)(4+3i)
= 16+12i-12i-9*i^2
=16+0-9(-1) {i^2 is -1 since, you know, i is square root of -1}
=16+9
=25

what is the lowest common multiple of 9 and 15?

Method 1:
9 18 27 36 45
15 30 45

Answer = 45

Method 2
9 = 3*3
15 = 3*5

LCM = 3*3*5 = 45

(15-r)! / (16-r)! = 1/3

OK ... first realize that 2!/3! = 1/3 ... in fact (n-1)!/n! = 1/n

So 15-r = 2 or 16-r = 3 ... either case r=13 ... no so lucky.

Two train going 40 and 50 mph for 3 hours.

One train goes 3*40 = 120 miles, while the other train goes 3*50 = 150 miles.

If they go in the same direction. One train will be behind the other by 150-120 = 30 miles.
If they go in opposite directions. They will be 120+150 = 270 miles apart.
If one goes south and the other goes east or west, we new to use the Pythagorean Theorem
square root ( 120^2 + 150^2) = 192.094

This is the commutative property of addition 8 + 63 = 63 + 8. There is also a commutative property of multiplication 8 x 63 = 63 x 8, but no commutative property of subtraction 8 - 63 NOT EQUAL 63 - 8 and no commutative property of division 8 / 63 NOT EQUAL 63 / 8.

-(-9) = +9 ... this is the same as -1 x -9 and mutiplying 2 negative numbers gives a positive result.

No. 8/25 does not equal 16/100.
what does equal 8/25, on the other hand, is 32/100.
why not try that?
