Answer:
28 x³ + 48 x² + 62 x + 30
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the polynomial equation
(4 x² + 4x +6)(7x+5)
Multiply
⇒ 4 x² ( 7 x+5) + 4 x ( 7x+5) + 6 (7x+5)
⇒ 28 x³ + 20 x² + 28 x² + 20 x + 42 x + 30
⇒ 28 x³ + 48 x² + 62 x + 30
6^5 because there are 5 six's being multiplied
Answer:
yes
Step-by-step explanation:
Answer:
78 mg
Step-by-step explanation:
370 mg - 110 mg = 260 mg (amount decayed in the 8 total years)
260 mg ÷ 8 years = 32.5 mg decayed per year
32.5 × 9 years (years between 2008 and 2017) = 292.5 mg
370 mg - 292.5 mg = 77.5 mg, rounded to 78 mg
