When they say to solve for c, they just want you to isolate it. We can start by subtracting b from both sides to give us:
x - b = cd
After this, we can divide both sides by -d to finish isolating the variable c; remember that -cd is -1(c)(d):
= c
Therefore, c =
Answer:
X=53. X=38
Step-by-step explanation:
46+81+x=180
X=180-127
X=53 degrees
31+112+x=180
X=180-143
X=37 degrees
The answer is 45 because you do parenthesis first which is 13.5-4.5=9 then you multiply 9×5=45 therefore the answer is 45.
Answer:
a^5x^5, 10a^5x^4, 40a^5x^3
Step-by-step explanation:
Use pascal's triangle for the first one
(2+x)^5 * a^5
= x^5a^5 + 5*2^1*x^4*a^5 + 10*2^2*x^3*a^5 ...
= a^5x^5 + 10a^5x^4+ 40a^5x^3 ...
For the expression to be factor-able the Discriminant , has to be greater or equal to zero
ax^2 + cx + b = 0
c^2 - 4 ab >= 0
(-3)^2 - 4 * 1 * b >= 0
9 - 4b >= 0
9 >= 4b
b <= 9/4 (2.25)
Pick any value in that range for ex:
0 , 2, -3, -6
