"Evaluate 7a" typically means to calculate the value of the expression by substituting a specific value for the variable "a." For example, if "a" is given as 3, you would substitute it into the expression to get 7 * 3, which equals 21. If no value for "a" is provided, the expression remains as 7a.

Evaluate 3 a plus 4 a 6?
3a + 4a +/- 6; take the 3a & 4a and combine them; 7a +/- 6 would be your answer as 6 cannot combine with 7a due to the variable. If 7a +/- 6 = 0, then subtract/add (respectively) the 6 depending on the operation. Therefore 7a + 6 = 0 turns to 7a = -6. Divide the 7 with the -6 to get the a alone; a = -6/7 or -0.8. Cannot be simplified.

Evaluate 3 a plus 4 a 6?
3a + 4a +/- 6; take the 3a & 4a and combine them; 7a +/- 6 would be your answer as 6 cannot combine with 7a due to the variable. If 7a +/- 6 = 0, then subtract/add (respectively) the 6 depending on the operation. Therefore 7a + 6 = 0 turns to 7a = -6. Divide the 7 with the -6 to get the a alone; a = -6/7 or -0.8.

Evaluate 7a if a equals 6?
42, because if there is nothing between the 7 and 'a' and 'a' equals 6 then the answer is 42.

Solve the equation 9a-a equals 19 plus 7a?
9a-a = 19+7a 8a = 19+7a 8a - 7a = 19 + 7a - 7a 1a = 19 a = 19

How do you factorise 7a2 -8ab?
Oh, what a happy little question! To factorize 7a^2 - 8ab, we can look for the greatest common factor, which is a. So, we can factor out an 'a' to get a(7a - 8b). And just like that, we've created a beautiful factorized expression that brings a sense of peace and harmony to our mathematical world.

7 x a?
7 x a is written as ' 7a ' In algebra Plus is shown as ' a + b ' Minus is shown as ' a - b' Multiplication is shown as 'ab' . NEVER a x b , as the 'x' may be confused with an unknown value. Division is shown as ' a/b ' , like a fraction. e.g. 6a^(2) + 5b - 2c/3 means Six multiplied to 'x' and them multiplied to 'x' again (squared). Then you 'add' five multiplied to 'b' , then you subtract two multiplied to 'c' and the whole '2c' is divided by '3'. The divisional three only refers to the '2c'. If you wanted to divided the whole expression by '3' , then you insert brackets. [ 6a^(2) + 5b - 2c ] /3 Note the position(s) of the 'square brackets'.
