2a + 3a = 5a
The GCF is 5a.
5a times 5a would equal 25a^2.
5a = a + a + a + a + a
5a = -5a + 5Add 5a to each side:10a = 5Divide each side by 10:a = 5/10 = 1/2
(5a)^2 or a^2+10a+25
5a or 4a squared
The answer depends upon what the "x" here means. x is commonly used in algebra to denote a variable. However "x" is also a symbol used to mean multiplication. If the first then 5xa means 5 multiplied by x multiplied by a. If the second then 5xa means 5 multiplied by a. This is usually written simply as 5a.
30-5a = 25
It is: 5a2
(5a)2 = 25a2
6b-5a = 1
