1) rewrite the equation by completing the square
(X+4)^2=9
2) what are the solution to the equation
Answer A= X=-4 plus and minus 3
Hello from MrBillDoesMath!
Answer: x = 2
Discussion:
As 3*ln(x) = ln (x^3) and 2 ln(4) = ln (4^2) the equation becomes
ln(x^3) + ln(4^2) = log(128) =>
ln (x^3 * 16) = log(128) =>
x^3 ^ 16 = 128 =>
x^3 = 128\16 = 8
If x cubed = 8, the the cube root is 2.
Thank you,
MrB
Answer:
Step-by-step explanation:
A coefficient is basically the number infront of a variable or term.
E.g. the coefficient in 7x is 7
The coefficient in 23y is 23
The coefficient in 43a is 43.
So for your question: 7a + 23b + 2c + 16,
The coefficients are 7, 23 and 2
The answer is x=16
Step-by-step explanation:
3x+4x+46+2x-10=180
9x+36=180
9x=144
X=16
