What is 3a plus ab plus 3c plus bc?
That factors to (b + 3)(a + c)
What percentage is a c minus?
A 100- 90 b 89- 80 c 79- 70 d 69- 60 f 50 -0
How do you factor ax-xb-ay plus yb?
Recall distributivity a(b + c) = ab + ac = (b + c)a and associativity (ab)c = a(bc) (a + b) + c = a + (b + c) as well as commutativity ab = ba a + b = b + a we are gonna need those. See for yourself when I applied each to learn the trick: ax - bx - ay + yb = (ax - bx) + (-ay + yb) = x(a - b) + -y(a - b) = (x - y)(a - b)
How do you factorise 2a plus 4b plus 8c?
2a + 4b + 8c = 2(a + 2b + 4c) You could also continue by factoring the inside of the parentheses a bit: 2a + 4b + 8c = 2(a + 2b + 4c) = 2(a + 2[b + 2c])
A negative number minus a negative number?
is a negative number plus another number...., but not neccessarily a positive number b/c the first number may be greater than the second e.g. -5-(-2) that is -5+2, which is -3 2 negatives make a positive
Factor ab minus 2ac plus b squared minus 2bc?
(b-c)(a+b)-ac
What is the quadratic equasion?
If your Problem is organized like this: A x squared plus B x plus C, the equation is: (B plus or minus the square root of(B squared minus 4 A C)) over 2A
If you know that AB plus B equals C what is the conclusion?
C minus B equals AB
What is the letter grade of a 2.991 GPA?
It depends on the school's grading system, and whether the school uses plus or minus grades. Thus, it could be either a C+ or B-.
Is a 2.7 for the first year in college a good GPA?
It's average. Mostly they say a 2.0 is average, but in reality because of grade inflation a 3.0 is more like average in college. You're not failing, but it'd be better if you could pull your average up above 3.0.
If vector c equals vector a plus vector b under what circumstances does c equal a minus b?
When b is zero.
If a minus b equals c then what does b minus a equals?
a - b = c -(a - b) = -c b - a = -c
Find the numerical value for each symbol... a plus a plus a plus b equals a plus a plus b plus b plus b equals c plus c c minus a equals 6 What is the answer to this?
A=8 B=4 C=14 Yes, I know I'm a genius. Mak - the all knowing one. MWAHAHAH!
If you have a average score of 71.50 what does it equal in a GPA?
For schools that grade on the plus system it would be a C+. For those on a minus system B-.
What is b plus b plus b plus c plus c plus c plus c?
b+b+b+c+c+c+c =3b+4c
B plus b plus b plus c plus c plus c plus c equals?
b + b + b + c + c + c + c = 3b + 4c
How is a plus b over a minus b equals c plus d over c minus d?
(a + b)/(a - b) = (c + d)/(c - d) cross multiply(a + b)(c - d) = (a - b)(c + d)ac - ad + bc - bd = ac + ad - bc - bd-ad + bc = -bc + ad-ad - ad = - bc - bc-2ad = -2bcad = bc that is the product of the means equals the product of the extremesa/b = b/c
