Answer:
The answer is the middle one. The one starting with 27...
Step-by-step explanation:
Hope this helps!
I believe it's 9x2-12x+4 but I'm not quite sure cause we haven't yet gone over this in class.
My friend also believes it is this (she's in a higher level math grade than me). I'm so sorry this isn't more helpful.
Answer:
5 inches
Step-by-step explanation:
Since the length of the sides of a cube are all equal,
volume of cube
= side ×side ×side
= (side)³
125= (length of side)³
Cube root both sides:
Length of each edge
![= \sqrt[3]{125}](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%5B3%5D%7B125%7D%20)
= 5 inches
Answer:
23. 16x² + 4x + 0.25
24. 16x² - 4x + 0.25
Step-by-step explanation:
Given the functions f(x) = 4x + 0.5 and g(x) = 4x - 0.5, questions 23 and 24 are asking you to square the entire function. So, you will take the expression given in each function and square it:
(f(x))² = (4x + 0.5)(4x + 0.5) Using FOIL:
(4x*4x) + (4x*0.5) + (4x*0.5) + (0.5*0.5)
16x² + 2x + 2x + 0.25 = 16x² + 4x + 0.25
(g(x))² = (4x - 0.5)(4x - 0.5) Using FOIL:
(4x*4x) - (4x*0.5) - (4x*0.5) + (0.5*0.5)
16x² - 2x - 2x + 0.25 = 16x² - 4x + 0.25
Answer:
This is FALSE. Choose Option 2
Step-by-step explanation:
Substituting 7 for x, we get
7 + 9(7) > 73, or 70 73. This is FALSE. Choose Option 2
