Answer:
x = 7, -7
Step-by-step explanation:
(2x-1)(3x+2)+x+292
3x - 2x +x = 2 - 1 + 292
(6)x - 294 = 6(x - 49)
Use communicative property of multiplication
Example: (A+B)(A-B)
49 is the square of 7
x square is the square of x to the power of 1
(x+7)(x-7)
Answer:
12 - p
Step-by-step explanation:
12 - p
Answer:
Step-by-step explanation:
Well, the ratio of yellow beads to blue beads is 4:5. The best way I think is to guess and check multiplying the ratio by integers. You need between 15 and 20.
4 : 5 ( = 9 too little )
8 : 10 ( = 18 just right)
12 : 15 ( = 27 too much)
So per necklace, 8 yellow beads and 10 blue beads would be needed.
I hope this helps :-)
Meaning of the rate: 6 days each month.
The answer is A. Something happens 6 days per month.
This means that in every month, there are available 6 days that let you do something.
Example in the GYm, you have 6 days per month free gym usage.
Answer:
d) This is a completely randomized design with two explanatory variables (factors).
Step-by-step explanation:
Explanatory variables are independent variables.
In this case, I prepared two explanatory variables, which are : (i)30-second ad
(ii) 60-second ad,
Then, the explanatory variables were assigned to 4 treatment groups, and each variable is done once or thrice.
All subjects are assigned randomly to all treatment groups, with each treatment group seeing one. We can conclude that this is a completely randomized design with two explanatory variables.
