Answer:
D
Step-by-step explanation:
B = (2 8)
(0.6 3)
CF = (-21 1.5)
(12 -41)
B - CF = (2-(-21) 8-1.5)
(0.6-12 3-(-41))
B - CF = (23 6.5)
(-11.4 44)
Answer:
B
Step-by-step explanation:
If C is the correct answer and if the final result is multiplied out, where does the minus sign in a^4 - b^4 come from? All pluses don't make a minus. A is incorrect.
If D is correct, then a^2 - b^2 should be further factored producing a different kind of answer, like (a + b)^2(c-d)^2 which is not the same as a^4 - b^4. So D is not correct.
The first step in factoring a^4 - b^4 is (a^2 + b^2)(a^2 - b^2) A doesn't lead you anywhere. A is incorrect. The answer must be B.
a^4 - b^4 = (a^2 - b^2)(a^2 + b^2) The first term factors.
a4 - b^4 = (a + b)(a - b) (a^2 +b^2)
X=16
move constant to the right side and change its sign 2x=27(+5)
add the numbers 2x=32
x=16
Answer:
<em>This will occur again in 15 more days.</em>
Step-by-step explanation:
Simply divide 15 by 3, which equals 5, in which makes it the least common multiple of 5 and 3.
