Answer:
3150mm
Step-by-step explanation:
1cm is 10mm you convert it then times it together l x b x h will equal 3150
The value of the function (f.h)(x) is 96x⁵ + 132x⁴ + 78x³ + 18x²
<h3>How to solve function?</h3>
f(x) = 3x² + 4x³ + 8x⁴
g(x) = -3x + 12x² - 5x³
h(x) = 12x + 6
Therefore,
(f.h)(x) = f(x).h(x)
Hence,
f(x).h(x) = (3x² + 7x³ + 8x⁴)(12x + 6)
f(x).h(x) = 36x³ + 18x² + 84x⁴ + 42x³ + 96x⁵ + 48x⁴
(f.h)(x) = 96x⁵ + 84x⁴ + 48x⁴ + 36x³ + 42x³ + 18x²
(f.h)(x) = 96x⁵ + 132x⁴ + 78x³ + 18x²

Noah is right the answer is 6.9
Answer: 40 stamps
Step-by-step explanation:
Let Maddy = M and Simon = S
Given that maddy had twice as many stamps as simon. That is,
M = 2S ....(1)
After maddy sold 60 stamps, simon had twice as many stamps as maddy. That is,
S = 2( M - 60) .... (2)
Substitutes M for 2S from equation (1) into equation (2)
S = 2( 2S - 60 )
Open the bracket
S = 4S - 120
Collect the like terms
S - 4S = -120
- 3S = - 120
S = 120/3
S = 40
Substitute S into the equation (1)
M = 2 × 40 = 80
Maddy has 80 - 40 = 40 stamp
Therefore, Maddy has 40 more stamps than simon in the beginning.
