Answer: The answer would be 3i
Step-by-step explanation: Absolute value is the magnitude of the real number meaning -3=3 or 3=3.
Multiply out as indicated: <span>9(r - s) + 5(2r - 2s) = 9r - 9s + 10r - 10s. Next, combine like terms, obtaining 19r -19s (answer)</span>
No, none of the shapes are regular. A regular shape is one that has all equivalent sides and equal angles
A polynomial with a degree of 3 is understood to have three zeroes or roots. In the given problem in 1, x3 + 6 x2 – 9x – 54, the roots of the polynomial using the calculator are B. B. 3, -3, -6. The same applies for number 2 given the polynomial x3 – 4x2 + 3x – 12. The answer in 2 is D. 4 years. The roots of the polynomial in 3 are:
<span>x1=−0.45117</span>
<span><span>x2</span>=1.77474</span>
<span><span>x3</span>=0.03821+0.70576∗i</span>
<span><span><span>x4</span>=0.03821−0.70576∗i. Hence there is A. 1 negative root.</span></span>
First add 2 2/4 and 1 3/4
= 4 1/4
Then subtract 4 1/4 from 12
= 7 3/4
