Answer:
45
Step-by-step explanation:
(1×4)+1=5
(2×5)+2=12
(3×6)+3=21
(5×8)+5=45
right?
Step-by-step explanation:
The polynomial x³ + 8 is equal to (x + 2)(x² - 2x + 4)
= (x + 2)(x² - 2x + 4)
= x³ - 2x² + 4x + 2x² - 4x + 8
= x³ + (-2 + 2)x² + (4 - 4)x + 8
= x³ + 8
Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000368
mm, while the length of the second strain measures 0.000000064 mm. How much larger is the first strain than the second?
We can figure this out using scientific notation.
Put 3.04e-7 in standard notation.
Put 0.00000304 back into scientific notation, instead with a multiply sign.
Move the dot back, making the number in between 1-10.
In this case, we would move it back 7 times.

So the answer would be A.
A.
Cause the y and x you get from solving the system, is the intersection point :)
Written like this (x, y)
To be able to give the answer to this item, we are to represent first with any variables the amount he earns each weekend for mowing the same field. Also, we represent the number of weeks he had worked by the variable y. The total amount of money he will have after working for y weeks is,
T = xy
Since, we are not given with any other information of the other expenses that have to be paid then we can say that if T is already equal to the price of the new lawnmower then, Tom will be able to purchase it and begin his lawn mowing business in due time.
