(L · W · 2) + (perimeter of the base · height). For this prism, that's (2 cm · 3 cm · 2) + (2 cm + 2 cm + 3 cm + 3 cm) · 6 cm. This is (12 cm2) + (10 cm · 6 cm) = <span>72 cm2.</span>
Step-by-step explanation:
There is nothing special in the given expression.
first of all we can arrange the likes terms together to reduce the expression, and there is no need of parenthesis so we can write
4a+4b+2b-c+5c
=4a+4b+4c
taking 4 common we get
4(a+b+c)
5 - 1 2/9 = 3 7/9
Hope this helps!
Answer 20 I just did that question
Answer:
(f+g)(x) = 60x + 400
Step-by-step explanation:
Given :
Amount in account A:
f(x) = 20x + 100
Amount in account B :
g(x) = 40x + 300
Total amount in Account A and B:
f(x) + g(x) = (20x + 100) + (40x + 300)
(f+g)(x) = (20x + 40x) + (100 + 300)
(f+g)(x) = 60x + 400
