First of all,

let the two zeroes be 2 and 3.

Now,

Sum of the zeros = 2 + 3 = 5

Product of the zeros = 2 × 3 = 6

Hence, the polynomial formed is,

= x² – (sum of zeros)x + Product of zeros

= x² – 5x + 6

Answer:

11. $b = 30$

Step-by-step explanation:

$a^{2} + b^{2} = c^{2}$

Substitute

$16^{2} + b^{2} = 34^{2}$

$256 + b^2 = 1156$

$b^2 = 1156-256\\b^2 = 900$

$b = \sqrt{900}$

$b = 30$

Your welcome and don't forget to say <u>Thanks</u>

Angie and Becky each completed a separate proof to show that the measures of vertical angles AKG and HKB are equal. Who complete

Helga [31]

Answer:

Becky, because her justification for the second statement should be "definition of supplementary angles" rather than "angle addition postulate."

Step-by-step explanation:

Becky completed the proof incorrectly because her justification for the second statement is not totally correct.

Angle addition postulate does not really apply here, as the sum of 2 angles may not give you exactly 180°.

However, the second statement, m<AKG + m<GKB = 180° and m<GKB + m<HKB = 180°, can be justified by the "Definition of Supplementary Angles".

The sum of supplementary angles = 180°.

Therefore, Becky completed the proof incorrectly.

What mistake did she make?

tiny-mole [99]

Step-by-step explanation:

According to the pythagrean equation, it should be

$AC^2 = AB^2 + BC^2\\$

8² = 6² + BC²

64 = 36 + BC²

BC² = 28

BC = ✓28 = 5.29
