Answer:
(negative 7 x + 4)(negative 7 x minus 4)
Step-by-step explanation:
Consider two real numbers a and b. A difference of squares involving a and b is usually given as;
The difference of the two squares above can be factored to yield;
This implies that in order to have the difference of squares we must have a product involving the difference and the sum of the numbers.
The expression;
(negative 7 x + 4)(negative 7 x minus 4) can also be written as ( 4 - 7x) ( -4 - 7x)
( 4 - 7x) ( -4 - 7x) = ( 4 - 7x) (-1( 4 + 7x)) = -1 *( 4 - 7x) ( 4 + 7x)
Expanding the last expression yields;
-1 (16 + 28x -28x - 49x^2) = -1 (16 - 49x^2) = 49x^2 - 16 which is in deed a difference of squares
Answer:
No
2.99/6 = about fifty cents a drink.
(sorry if its not right I havent done this kind of math in like 3-5 years lol)
So.. 55x3=165
165 is already in its simplest form I don’t think you can square root it
Find how many times 2/3 can go into 12.
In other words, divide 12 by 2/3.
12/(2/3)
Note that dividing is equal to multiplying by the reciprocal. So...
12/(2/3) = 12 * 3/2 = 18
