Answer: cd(x) = 4x³ — 2x² + 8x — 4
Step-by-step explanation:
c(x) = 4x - 2
d(x) = x² + 2
Therefore, cd(x) = c(x) × d(x)
cd(x) = (4x - 2)(x² + 2)
= (4x × x²) + (4x × 2) + (-2 × x²) + (-2 × 2)
= 4x³ + 8x -2x² - 4
cd(x) = 4x³ — 2x² + 8x — 4
Hope this helps?
Answer:
10a^2 - 19a + 7
Step-by-step explanation:
Use the FOIL method to multiply these binomals together. We get:
10a^2 - 14a - 5a + 7.
Combining the 'a' terms, we get
10a^2 - 19a + 7
Answer:
The angles are: 50.3 and 129.7
Step-by-step explanation:
The sum of supplementary angles is 180°.
Let x be one angle then the other angle will be x+79.4
Using the supplementary angle sum
For the measurement of 2nd angle
x+79.4 => 50.3+79.4 => 129.7
Hence,
The angles are: 50.3 and 129.7
If this is greater than the first part of the number called by the spectator (i.e., ignoring the last two digits), then the last digit of your answer is the lower of the two possible values. Otherwise the last digit is the higher value. For example if the number called is 2809, the square root could be either 53 or 57.
