What is 3b-8b?
3b-8b = -5
How do you factor 8b2-9b plus 1?
8b^2 -9b +1 8b^2 -8b -b +1 8b(b-1) - 1(b-1) (8b-1)(b-1)
What is 7a plus 8b times 2 if a equals 3 and b equals 4?
7(3) + 8(4) x 2 21 + 32 x 2 43 x 2 86 The final answer is 86.
If 8a x 8b equals 8c divided by 8d what is d in terms of a b c?
(8a)(8b) = (8c)/(8d); multiply both sides by 8d to obtain (8a)(8b)(8d) = (8c); divide both sides by 8 to obtain (8a)(8b)d = c; divide both sides by (8a)(8b) to obtain d = c/[(8c)(8b)].
What is the answer of 23 plus 8b equals -42?
8b = -65 so b = -8.125
What is 14b plus 3 plus 8b?
22b + 3
How do you factor 3x plus 8b times 9x2 - 24xb plus 64b2?
One of the factors is 3x + 8b. The other is 9x^2 -24xb + 64b^2
What is 8b - 12c?
8b - 12c = -4
What is 3b-8b?

They are 3 terms of an algebraic expression
How do you factor 8b2-9b plus 1?
8b^2 -9b +1 8b^2 -8b -b +1 8b(b-1) - 1(b-1) (8b-1)(b-1)
What is -8b-48a-40c?
-8b-48a-40c
What is 8b minus 4b?
8b - 4b = 4b
If 3a plus 2b equals 24 and 4a plus 8b equals 70 how do you solve for a and b using the elimination method?
Two equations, two unknownsFirst, multiply 3a + 2b = 70 by 4. This gives the equation 12a + 8b = 96. Next, subtract 4a + 8b = 70 from this equation. This result gives 8a = 26, which, solving for a, gives a = 3.25.Substitue the value of a into one of the original equations, which will give b = 7.125.Finally check your results by substituting the values of a and b into each equation.Answer:Given two equations 3a + 2b = 24 ------ (1) and 4a + 8b = 70 ------ (2) We have to solve this by using elimination method.Multiply the equation 3a + 2b = 24 by 4 on both the sides.We get 12a + 8b = 96 ---------- (3)Now, subtract the equation (2) from equation (3)12a + 8b = 96 ---------- (3)4a + 8b = 70 ---------- (2)--------------------------------(12a - 4a) + (8b - 8b) = (96 - 70)8a + 0 = 268a = 26a = 26/8a = 13/4 (Or) a = 3.25Substitute the value of a in the equation (2)4a + 8b = 70 ---------- (2)4(13/4) + 8b = 70.13 + 8b = 708b = 70 - 138b = 57b = 57/8 (Or) b = 7.125
What is the factor of the expression 121A2-64B2?
(11a + 8b)(11a - 8b)
6a plus 7b - 4a - 8b equals?
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
What is b - 9b simplified?
What I would do is change the problem up. Instead of b-9b I would make it -(9b-b). It is still the same problem; you will multiply the number inside the parenthesis be -1. So start with 9b-b. That would equal 8b. So it would change from -(9b-b) to -(8b) so you multiply 8b by negative 1 (-1) to get the answer -8b. -8b is your answer. So b - 9b = -8b
