The difference between the roots of the quadratic equation x2 -14x +q =0 is 6. Find q

Irina-Kira [14]

9514 1404 393

Answer:

q = 40

Step-by-step explanation:

When the quadratic has roots p and r, it can be factored as ...

(x -p)(x -r) = x² -(p+r)x +pr

So, the sum of the roots is 14, and their difference is 6. This lets us find the roots from ...

p + r = 14

p - r = 6

2p = 20 . . . add the two equations

p = 10

r = 14 -p = 4

The value of interest is then ...

q = pr = (10)(4)

q = 40

The graph shows the roots to be 4 and 10, as we found.

ABCD ~ EFGH

vredina [299]

Answer:

FG = 20 in

Step-by-step explanation:

∵ ABCD ≈ EFGH

∴ AD/EH = BC/FG

∵ AD = 45 in

∵ EH = 60 in

∴ BC = 15 in

∴ 45/60 = 15/FG

∴ FG = (60 × 15) ÷ 45 = 20 in

You can solve them in the same way. you can add any positive or negative number to both the sides of an inequality.Also you can multiply or divide both sides of an inequality by any positive number hope this helps. :)
