Answer:
7 x 7 x 7= 49 x 7= 343
3 x 3 x 3 x 3= 9 x 3 x 3= 27 x 3= 81
I think the trick is to add the two middle terms together. (And the 2 end terms).
8 - 12x
The variable is x. The coefficient is - 12.
8 is a constant.
The coefficient always goes with a variable.
3x^2 + 2x + 5
Nothing can be combined. The leading coefficient is 3 (which goes with the greatest power of the variable x^2 in this case) and the other coefficient is 2. 5 is a constant.
Answer:
radius is 8cm
Step-by-step explanation: radius is half of diameter so 16/2= 8
Answer:
volume = 1/24 cm^3
Step-by-step explanation:
Volume = lwh
(1/2)(1/4)(1/3)=1/24
Therefore, volume = 1/24 cm^3
I hope this helped and have a good rest of your day!
Answer:
4x -2y + 8z
Step-by-step explanation:
10 / 4 = 4x
-5y / 2.5 = -2y
20z / 2.5 = 8z
resulting in 4x -2y + 8z.
