Answer:ITS 465
Step-by-step explanation:
4 + 6 + 5 = 15
AND THE DIFFERENCE IS 2 BETWEEN 6 AND 4
Answer:
r = 105
Step-by-step explanation:
Given quadratic equation:
x² − 9x − 6
Quadratic formula is given by:
(-b ± √b² - 4ac) ÷ 2a
For the equation: x² - 9x - 6
a = 1, b = -9 and c = -6
Substitute in the quadratic formula:
(-b ± √b² - 4ac) ÷ 2a
(-(-9) ± √(-9)² - 4(1*-6)) ÷ 2*1
= 9 ± √105 / 2
The solution of x² − 9x − 6 is expressed as 9 plus or minus the square root of r, all over 2
Therefore, the value of r is 105
Answer:
x=-20/7 or -2.857
Step-by-step explanation:
bring like terms together in each side of the = side
then work the out
4x + 6y = 8z +34
4x+6y - 8z = 34
