Answer:
C & F
Step-by-step explanation:
29 - 13 is 16 and 46 - 21 is 25. Everything else is wrong because the differences are not the correct answers except for C and F. Sorry if this sounds kinda confusing
This is probably wrong so...
Volume/V=length x width x height
So, V=4.5 x 2 x 2
V =18
Answer:
4x(x - 1)
Step-by-step explanation:
Factor the numerator and denominator
64
- 64x ← factor out 64x from both terms
= 64x(
- 1) ← difference of squares
= 64x(x² - 1)(x² + 1) ← x² - 1 is also a difference of squares
= 64x(x - 1)(x + 1)(x² + 1)
---------------------------------
(8x² + 8)(2x + 2) ← factor out 8 and 2 from each factor
= 8(x² + 1) × 2(x + 1)
= 16(x² + 1)(x + 1)
Then expression can be written as
← cancel (x² + 1) and (x + 1) on numerator/ denominator
= 
← cancel common factor 16 on numerator/ denominator
= 4x(x - 1)
Question 6
first multiply the numerator and
denominator by 9+(2)^1/2
Question 7
Acceleration is the change in velocity over time. There's are formula's for such problems which are called kinematics equations. Look em up. One of them doesn't have t (time) in them you would normally use that one to solve this problem. 16/2/20=a=0.4m/s^2
I did it for you but please look it up, understand and memorize it ;)
