If f of x equals 3x - 10 then what is f of 2a?
if f(x) = 3x - 10, then whatever is put (substituted) for x in the "f(x)" bit is substituted for x in the "3x - 10" bit. Thus f(2a) = 3(2a) - 10 = 6a - 10.
What is 9a plus 8-2a-3-5a?
9a +8 -2a -3 -5a = 2a +5
How do you find the sum or difference of (5a2 plus 6a plus 2)-(7a2-7a plus 5)?
Combine like terms, adding/subtracting the coefficients: (5a² + 6a + 2) + (7a² - 7a + 5) = (5+7)a² + (6-7)a + (2+5) = 12a² - a + 7 (5a² + 6a + 2) - (7a² - 7a + 5) = (5a² + 6a + 2) + (-7a² + 7a - 5) = (5-7)a² + (6+7)a + (2-5) = -2a² + 13a - 3
9a equals 6a plus 4?
9a = 6a + 4 subtracting 6a from each side, 3a = 4 dividing each side by 3, a = 4/3
What is 2a plus 3b?
2a + 3b
What is 2a times 3?
Since the question is 3(2a), then just write it out. 3(2a) is 2a+2a+2a or 6a.
What is 2A times 3 equals 8 plus 4A?
2a*3 = 8+4a 6a = 8+4a 6a-4a = 8 2a = 8 a = 4
What is the answer to 6a-3 equals 8a plus 11?
6a-3=8a+11 -3-11=8a-6a -14=2a a=-7
What is the factor of 6a squared - 17a plus 12?
(2a - 3)(3a - 4)
6a - 5b equals 9 2a plus 5b equals 23?
(4, 3)
-8a plus 6a plus 7 equals 1?
-8a + 6a + 7 = 1 -2a = 1 - 7 -2a = -6 a = 6/2 a = 3 Check: -8(3) + 6(3) + 7 = 1 -24 + 18 + 7 = 1 1 = 1
How do you factor 2a squared 6a?
I guess you mean: 2a^2+6a Well in this case you take 2a out of the bracket and then you're left with a+3 inside. 2a(a+3a)
When 3a2-2a plus 5 subtracted by a2 plus a equals 1?
Not sure why it is 3a2- if you mean 3*a*2, then: 3*a*2=6a (6a-2a)+5-2(a (or a2)+a)=1 4a+5-(2a+a)=1 4a+5-2a-a=1 Then take the 5 over (remember, the +5 become -5 when transposed): 4a-2a-a=1-5 Solving the equations on both sides gives: a=-4 Is this your answer?
If f of x equals 3x - 10 then what is f of 2a?
if f(x) = 3x - 10, then whatever is put (substituted) for x in the "f(x)" bit is substituted for x in the "3x - 10" bit. Thus f(2a) = 3(2a) - 10 = 6a - 10.
6ab plus 9b divided by 2a plus 3?
(6ab + 9b)/(2a + 3) = 3b(2a + 3)/(2a + 3) = 3b
What is the answer to (2a plus 3)?
It is the expression 3 + 2a.
2a -3 plus 4b - 2a -b -3 plus 5?
2a-3+4b-2a-b-3+5=3b-1
