The number is 4 2/5.

Setting up the equation, we have
x/11 = 2/5

Multiply both sides by 11:
x = 2/5(11) = 2/5(11/1) = 22/5 = 4 2/5

Solve 2x2 + 26 = 0 to identify the roots.

Answer:

$x=+/-i\sqrt{13}$

Step-by-step explanation:

To find the roots, factor and set equal to 0 or use the quadratic formula. This quadratic equation does not factor and must be solved using the quadratic formula.

$x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}$

where a = 2, b=0, and c=26

$x=\frac{0+/-\sqrt{0^2-4(2)(26)} }{2(2)} \\x=\frac{+/-\sqrt{-208)} }{4} \\x=\frac{+/-i\sqrt{16*13)} }{4}\\x=\frac{+/4i\sqrt{13} }{4}\\x=+/-i\sqrt{13}$

Answer:

a = 2

Step-by-step explanation:

If M is the midpoint, 1/2 of FG = FM since FG is the whole length.

FG = 14a + 1

1/2 FG = 1/2(14a + 1)

1/2 FG = 7a + 1/2

The length of the segment FM = 14.5 and that is the same length as 1/2 FG

7a + 1/2 = 14.5

1/2 = 0.5

7a + 0.5 = 14.5 Subtract 0.5 from both sides

7a = 14.5 - 0.5

7a = 14 Divide by 7

a = 14/7

a = 2
