15a - 54 equals -9 slove four a?
Add 54 to both sides and you get 15a = 45. I think a chimp could solve this one. (a=3)
What is the answer to this math problem -4 plus 2a equals 12-15a plus a?
-4 + 2A = 12 - 15A + A-4 + 2A = 12 - 16A2A = 12 - 16A + 42A = 16 - 16AA = 8 - 8A
What is 15a plus 25?
It is already in its simplest form, so it is: 15a + 25
What is 5a³ plus 15a² plus 20a?
It cannot be simplified any further, so it is: 5a³ + 15a² + 20a
What is sin23A minus sin7A upon sin2A plus sin14A if A equals pi upon 21?
Using the identity, sin(X)+sin(Y) = 2*sin[(x+y)/2]*cos[(x-y)/2] the expression becomes {2*sin[(23A-7A)/2]*cos[(23A+7A)/2]}/{2*sin[(2A+14A)/2]*cos[(2A-14A)/2]} = {2*sin(8A)*cos(15A)}/{2*sin(8A)*cos(-6A)} = cos(15A)/cos(-6A)} = cos(15A)/cos(6A)} since cos(-x) = cos(x) When A = pi/21, 15A = 15*pi/21 and 6A = 6*pi/21 = pi - 15pi/21 Therefore, cos(6A) = - cos(15A) and hence the expression = -1.
How do you factor 5a3-25a2 plus 15a equals?
5a(a(a-5)+3)
15a - 54 equals -9 slove four a?
Add 54 to both sides and you get 15a = 45. I think a chimp could solve this one. (a=3)
What is the value of x if 3ax - 4x equals 15a -20?
x would be 5.
What is the answer to this math problem -4 plus 2a equals 12-15a plus a?
-4 + 2A = 12 - 15A + A-4 + 2A = 12 - 16A2A = 12 - 16A + 42A = 16 - 16AA = 8 - 8A
How do you solve 7a-b equals 15a and solve for a?
-8
What are the factors of 15a 12?
15a + 12 = 3(5a + 4)
What is 15a plus 25?
It is already in its simplest form, so it is: 15a + 25
What is 15a squared divided by 3a?
5
What are the factors of 15a?
1,3,5,15,a
What are math expressions?
A math expression is basically and equation without and equals sign. For example "15a+30b" would be an expression, while "15a+30b=45c" would be an equation. An expression can also be defined as a sum of terms.it could also be defined as a mathematical phrase which involves or contain variables and numbers.like(x and y)these are variables.
