Step-by-step explanation:
Hey there!
Here,

While working with them remember some rules;
- (-) + (-) = sign (-) but add them.
- (+) + (+) = sign (+) and add.
- (+) - (+) = subtract but keep sign of greator number.
- (-) -(-) = subtract and keep the sign of greator number.

I would set this up as a a proportion:

17x = 1360
x = 20 cm
The factored form of the given expressions are
y = (x -2)(x +7)
y = (x +6)(x -9)
y = (x +2)(x +6)
y = (x -5)(x -6)
y = (x +5)(x -5)
y = (x -1)(x +9)
y = (x +4)(x -4)
<h3>Factoring quadratic expressions</h3>
From the question we are to factor the given quadratic expressions
y = x² +7x -2x - 14
y = x(x +7) -2(x +7)
y = (x -2)(x +7)
y = x² -9x +6x - 54
y = x(x -9) +6(x -9)
y = (x +6)(x -9)
y = x² +6x +2x +12
y = x(x +6) +2(x +6)
y = (x +2)(x +6)
y = x² -6x -5x +30
y = x(x -6) -5(x -6)
y = (x -5)(x -6)
y = (x +5)(x -5)
y = x² +9x -x -9
y = x(x +9) -1(x +9)
y = (x -1)(x +9)
y = (x +4)(x -4)
Hence, the factored form of the given expressions are
y = (x -2)(x +7)
y = (x +6)(x -9)
y = (x +2)(x +6)
y = (x -5)(x -6)
y = (x +5)(x -5)
y = (x -1)(x +9)
y = (x +4)(x -4)

If both triangles are similar the ratio of sides will be same

(-6)(-0.4)(-0.5) = (-1)6⋅4⋅5⋅10⁻² = -1.2
