6a add 21 = 27
What else can I help you with?
How do i you solve this equation 6A-58 equals 44?
6A - 58 = 44 Add 58 to both sides: 6A = 102 Divide both sides by 6: A = 17
How do you simplify 3a 4a - a?
Add them together: 3a+4a-a = 6a
How do you solve -21 equals 9a-15-3a?
-21 = 9a - 15 - 3a -6 = 6a -1 = a
How do you solve two step eqation 6a take away 4 equals negative 2?
6a - 4 = -2 Add four to both sides: 6a = 2 Divide both sides by 6: a = 1/3
How do you simplify this expression 12a - 6a plus a?
12a- 6a + a = 7a Since they all have the same variable, you can simply add and subtract 12-6 = 6 6+1 = 7
P equals 3a-3q then 6a equals?
P = 3a - 3q Add 3q to each side: P + 3q = 3a Double each side: 6a = 2P + 6q
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 6a squared plus 18ab?
Divide by 6a: 6a(a + 3b)
Factor 36a2-60a plus 25?
36a2 - 60a + 25 = 36a2 - 30a - 30a + 25 = 6a(6a - 5) - 5(6a - 5) = (6a - 5)(6a - 5) = (6a - 5)2
What is 10a-37 equals 6a 51?
10a-37=6a+51 -6a -6a subtract 6a from both sides and the 6a's cancel 4a-37=51 +37 +37 4a=88 /4 /4 a=22
What is 10a - 6a plus 2a?
6a
What is 12a - 6a plus a?
18
