Answer:
wow thats a lot let me write this down
Answer:
Step-by-step explanation:
x²+6x = 18
coefficient of the x term: 6
divide it in half: 3
square it: 3²
add 3² to both sides to complete the square and keep the equation balanced:
x²+6x+3² = 18+3²
(x+3)² = 27
x+3 = ±√27 = ±3√3
x = -3±3√3
Answer:
yes it is divisible by 8
Step-by-step explanation:
please mark me as brainlest is
Answer:
D
Step-by-step explanation:
yes it is.
start by multiply by 4 to get rid of the fraction on x
4 () = 4(4) + 4()
x = 16 + 8y/3
Then by 3 to get rid of that one
3(x) = 3(16) + 3()
3x = 48 + 8y
Then subtract 8y from both sides to get
3x - 8y = 48
Answer:
Step-by-step explanation:
When given the following equation;
One has to solve for the variable (x). Remember, when working with fractions, one must have a common denominator in order to perform operations. Since the denominators on the left side of the equation are unlike, one must change them so that they are like denominators. Multiply each fraction by the other fraction's denominator on the respective side. Remember to multiply both the numerator and denominator by the value to ensure that the equation remains true.
Simplify,
Distribute the negative sign to simplify the left side of the equation;
Since the denominators on opposite sides of the equation are like, one can now ignore the denominators,
