I used the distributive property.
Answer:
B = 25050
Step-by-step explanation:
S=n/2(2a1+(n-1)d)
Since
h(x) = g(f(x)), h'(x) = g'(f(x))×f'(x) (Chain rule).
Setting x=3 we get
h'(3) = g'(f(3))×f'(3)
Plugging in values we get
h'(3) = g'(4)×7
h'(3) = 2×7
h'(3) = 14
4 you will have 2.1 meters of wood left over
