1. Multiply length times width as if they were integer number:
Now place the decimal point. To do it we have to keep in mind that the result will have as many decimals as the sum of the decimals of each number. In this case, only the width had one decimal, it means that the result will only have one decimal:
Answer:
Step-by-step explanation:
(a³ - b³) = (a - b) (a² + ab + b²)
27x³ - 64 = 3³x³ - 4³
= (3x)³ - 4³ {a = 3x & b= 4)
Substitute in the above formula.
= (3x -4)([3x]² + 3x*4 + 4²)
= (3x - 4)(9x² + 12x + 16)
The expression 27x^3-64 factors to (3x-4) (9x^2+12x+16).
Find two points where the line intersects with an x and y value that are whole numbers.
The line crosses (0,3) and (-2,-1)
The slope is the change in Y divided by the change in x.
The change in Y is -1 - 3 = -4
The change in x is -2 - 0 = -2
The slope becomes -4 / -2 which simplifies to 2
The answer is D.
Defining variables
let n1 be the first number
n2 be the 2nd number
add them together, you get 218
n1+n2 =218
n1 is 47 less than n2
n1=n2-47
do some substitution
n2-47 +n2 = 218
solve for n2
then use n2 to figure out n1
The common difference, d, is 5 and the starting value, a, is 2.
