Answer:
<h2>35 -10√10 + 14√6 - 8√15</h2>
Step-by-step explanation:
(√2 + √3)² · (√5 - √2)²
use (a ± b)² = a² ± 2ab + b²
= [(√2)² + 2(√2)(√3) + (√3)²] · [(√5)² - 2(√5)(√2) + (√2)²]
= (2 + 2√6 + 3) · (5 - 2√10 + 2)
= (5 + 2√6)(7 - 2√10)
use FOIL: (a + b)(c + d) = ac + ad + bc + bd
= (5)(7) + (5)(-2√10) + (2√6)(7) + (2√6)(-2√10)
= 35 - 10√10 + 14√6 - 4√60
= 35 - 10√10 + 14√6 - 4√(4 · 15)
= 35 - 10√10 + 14√6 - 4 · √4 · √15
= 35 -10√10 + 14√6 - 4 · 2 · √15
= 35 -10√10 + 14√6 - 8√15
Answer:
9.5
Step-by-step explanation:
Well the constant proportionality is 9.5 because that is what makes p directly proportional to a, because when h increases, a increases, and when h decreases, a decreases.
Answer:
4
Step-by-step explanation:
Put 2 where x is and do the arithmetic.
f(2) = 10 -3∙2 = 10 -6
f(2) = 4
