Answer: a^2 - b^2 = (a-b)(a+b)</h3>
The order of the factors does not matter.
So (a-b)(a+b) is the same as (a+b)(a-b)
This is known as the difference of squares factoring rule.
You can FOIL out (a-b)(a+b) and you'd get a^2+ab-ab-b^2. Note how the ab terms cancel leaving us with a^2-b^2. This confirms we have the correct factorization.
Answer:
340 liters
Step-by-step explanation:
This means that Tapiwah raked x plus 5% of x leaves. Knowing that Tapiwah actually raked 357 liters, we can find the value of x as follows. So, Adam raked 340 liters of leaves.
Answer:
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary, so ...
∠B +∠D = 180°
(3x -4)° +(2x -6°) = 180° . . . . substitute given expressions
5x = 190 . . . . . . . . . . . . . . . . divide by °, add 10
x = 38 . . . . . . divide by 5
Then the angle measures are ...
∠B = (3·38 -4)° = 110°
∠D = (2·38 -6)° = 70°
