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:
48*52=2496/2=1248
Step-by-step explanation:
Triangle syprine=b*h/2
16*14=224/2=112
answer b is the most similar:48*52=2496/2=1248
48 is 3x>16
It’s currently in point-slope form. To convert...
y-7=-3/4x-(15/4)
y=-3/4x-15/4+7
y=(-3/4)x+(13/4)
