B. the middle half of the data set
Answer:
12x^2+9x^2-25 (quadratic equation)
a=12, b=9, c=-25
put this in quadratic formula
Step-by-step explanation:
Answer:
Progression: 11, 18, 25
Rule: Add 7
Step-by-step explanation:
Given
List of numbers: 8, 11, 13, 18, 25, 37
Sample Progression: 8, 13, 18; with common difference of 5
Required
Form a different progression using any three listed numbers
To solve this; we'll make use of trial and error methods;
<em>NB: I've tried several numbers; So, I'll just stick to the one that works</em>
To start with;
Select ->11
Add 7 to 11: 11 + 7 - > 18
Add 7 to 18: 18 + 7 -> 25
With the above illustration, we've successfully used three numbers (11, 18 and 25) to form a new progression and the rule is to add 7
Given the dimensions of locker box are length = 6 feet, width = 4 feet, and height = 10 feet.
Wayne wants to cover the box, so we need to find its total surface area. The box is in the shape of rectangular prism.
We know the formula for total surface area of rectangular prism is given as follows :-
T.S.A. = 2·(6 x 4 + 4 x 10 + 10 x 6) = 2·(24 + 40 + 60) = 2·(124) = 248 feet²
Surface Area = 248 squared feet
To cover the locker with waterproof covering, we needed to find the surface area of the box. As we multiplied two dimensions at a time in the formula, so the units are "squared feet".
Hence, option A is correct i.e. squared feet or ft².
I will show you how to do the first one.....we are finding the GCF...the largest number that goes into each number (same for variables)
1.) 20yx , 80x³ ( factor each number and variable)
20 = 2, 4, 5, 10, 20
y = y
x = x
80 = 2, 4, 5, 8, 10, 16, 20, 40, 80
x³ = x, x, x
what is the largest number that 20 and 80 have in common? 20...
how about the variables? x
so, the Greatest Common Factor (GCF is 20x)
