Answer:
f(x) + g(x) = x^2 + 4x + 35
Step-by-step explanation:
Add like terms from f(x) and g(x):
f(x) + g(x) = x^2 + 3x + 28 + x + 7, or
f(x) + g(x) = x^2 + 4x + 35
Answer:
729 cubic meters
Step-by-step explanation:
Volume of cube is given by side^3
where side is length of the side
Given in the problem
side is 9 meters as length, width, and height of fort is 9 meters and it is in cube shape .
Thus,
volume of cube = 9^3 = 9*9*9 = 729
Thus, volume of Haley's fort is 729 cubic meters.
He started with 42 cards.
27-6= 21
21×2= 42.
Hope this helps! :)
