Answer:
5 inches
Step-by-step explanation:
(5 + x)(10 + x) = 6x²
x² + 15x + 50 = 6x²
5x² - 15x + 50 = 0
x² - 3x + 10 = 0
(x - 5)(x + 3) = 0
x = 5, x = -3
We want x to be positive, so x = 5.
Thus, each dimension must be increased by 5 inches.
.25x54=13.5 163x1.25=203.75 13.5+203.75=217.25
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
Actually Welcome to the Concept of the straight lines.
y-y1 = m(x-x1) + C
====> y - 1 = 3(x - 2)
====> y-1 = 3x -6
====> y = 3x - 5
hence the equation is y = 3x - 5
