Answer:
(x +6 ) ( x- 6)
Step-by-step explanation:
Well, this is absolute value, so as a mixed fraction you would have to times the denominator to the whole number, and then add the answer of that to the numerator (2 x 2 x 1). After that, you should get a whole number as an answer, but make it as a fraction. (put the whole number you got on top of the denominator before (2) to make it a fraction). Then, again, since it's absolute value, then it into a negative. Hope this helps and hope it not confusing!!
Answer:
Step-by-step explanation:
velocity of river with respect to ground = 4 mi/h south
Velocity of swimmer with respect to river = 2 mi/h east
According to the formula of relative velocity
Where, V(S,G) be the velocity of swimmer with respect to ground, it is true velocity of swimmer.
Answer:
a) The formula for the area of a circle
Step-by-step explanation:
The formula for the area of a circle is
A = πr²
π is an irrational number and, no matter what value you use for r, the area will be an irrational number,
b) is wrong. A = ½(a + b)h.
c) is wrong. A = ½bh.
d) is wrong. A = bh.
All measurements are rational numbers, so the areas will be rational numbers.
