Simple algebra, 2a-20 = -2 2a=18 a=18/2 a=9
What is 2a 2a in a maths term?
In mathematical terms, "2a 2a" typically implies the expression ( 2a \times 2a ), which can be simplified to ( 4a^2 ). This is derived from multiplying the coefficients (2 and 2) and adding the exponents of ( a ) (1 + 1). Therefore, the final result is ( 4a^2 ).
How do you solve -2a plus 5 equals 1?
-2a + 5 = 1 -2a = -5 + 1 -2a = -4 a = -4/-2 a = 2
What is 5a plus 3 plus 2a-2 plus a?
5a + 3 + (2a - 2) + a= 5a + 3 + 2a - 2 + a= 8a + 1
How do you simplify 2a plus 10 plus 5a-2?
2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
How do you solve 2a-7 equals -9?
2a - 7 = -9 2a - 7 + 7 = -9 + 7 2a = -9 +7 2a = -2 2a/2 = -2/2 a = -2/2 a= -1
How do you solve for the variable b in 2a plus 2b equals c?
2a + 2b = c subtract 2a from both sides 2a - 2a + 2b = c - 2a 2b = c - 2a divide both sides by 2 (2/2)b = (c - 2a)/2 b = (c - 2a)/2 --------------------
What is 2a divide by a?
2a ÷a = 2
2a-20 equals -2?
Simple algebra, 2a-20 = -2 2a=18 a=18/2 a=9
What is 2a-4b?
2a-4b = -2
How do you solve -2a plus 5 equals 1?
-2a + 5 = 1 -2a = -5 + 1 -2a = -4 a = -4/-2 a = 2
2a x 2a?
When you multiply 2a by 2a, you are essentially multiplying 2 by 2 and a by a separately. This results in 4a^2, where the coefficient 4 is the product of 2 and 2, and a^2 represents a multiplied by a. Therefore, the final answer is 4a^2.
What is 2a x a?
2a2
What would a be if 2a plus 12 equals 8?
2a+12=8 2a=-4 a=-2 So a is -2.
I have got a maths question that tells me to simplify a divided by 2a squared How?
a/2a^2 You can take "a" out of both of those. It leaves you with 1/2a
What is 5a plus 3 plus 2a-2 plus a?
5a + 3 + (2a - 2) + a= 5a + 3 + 2a - 2 + a= 8a + 1
How do you simplify 2a plus 10 plus 5a-2?
2a + 10 + 5a - 2 = (2a + 5a) + (10 - 2) = 7a + 8
