3 - 5 = -2 and 7 - 9 = -2. Therefore, nothing has to be changed.
<h2>
Hello!</h2>
The answer is C. formulas
<h2>
Why?</h2>
Formulas are laws o conditions that help us when we are solving numerical problems, we use them to relate number/variables in order to found equivalence between what we are calculating and the information we have.
A formula can include constants, variables and always contain an equality, this last one will help us to establish the needed equivalence to solve numerical problems.
Discarding the other given options:
A. decimals: Incorrect, decimals are a type of number which is not whole numbers.
B. graphs: Incorrect, graphs are graphical tools that we can use to show information or data.
D. percentages: Incorrect, percentages are used to show numerical information as a fraction of 100 units.
E. fractions: Incorrect, like decimals, fractions are a type of number which is not whole numbers, fractions are represented by a division of a number into another, representing just a part of a determinate whole number.
Have a nice day!
Answer:
The composite area is a total of 62 square inches.
Step-by-step explanation:
You're given three rectangles of different width and height. To find the correct answer, you need to find the sum of each rectangles' area.
first though we need to find the height of the middle rectangle. We are told the total height and the other two rectangles' heights, so we just need to subtract the others' heights from the total:
10 - (4 + 1.5)
10 - 5.5
= 4.5
So the middle rectangle is 4x4.5 inches, giving it an area of 18 square inches
The top one is 8x4 inches for a total of 32 square inches.
And the bottom one is 1.5x8 inches, for a total 12 square inches.
If we add them all up, that's 18 + 32 + 12 square inches, or 62 square inches.
Answer:
m = 2
Step-by-step explanation:
Given:
x = 4
y = 6m - 2
a = 8
b = 5
Required:
Value of m
SOLUTION:
x and y are segments of a chord divided when it intersects another chord that also has segments a and b.
According to the Intersecting chords theorem, 
Thus:
Solve for m
The value of m = 2
Differentiate the given solution:
Substitute 
and 
into the ODE:
and it's easy to see the left side indeed reduces to 0.
