Answer:
D) Jack made a mistake while squaring first term, 16x^2 - 8x +1
Step-by-step explanation:
we apply (a-b)^2 formula
a= 4x and b= 1
Replace 'a' with 4x and 'b' with 1
(4x)^2 is 16x^2
Jack made a mistake while squaring first term
(4x)^2 is 4^2x^2 that is 16x^2
Answer:
Step-by-step explanation:
5x
Answer: k = -1/3
Step-by-Step Explanation:
=> 3x - 2ky + 4 = 0
Value of ‘x’ = -2
Value of ‘y’ = 3
Substitute values of ‘x’ and ‘y’ :-
=> 3x - 2ky + 4 = 0
= 3(-2) - 2k(3) + 4 = 0
= -6 - 6k + 4 = 0
= -6k = 6 - 4
= -6k = 2
= k = 2/-6
=> k = -2/6 = -1/3
Therefore, k = -1/3
Answer:
see explanation
Step-by-step explanation:
f(x) × g(x)
= 11(123x - 40) ← distribute
= 1353x - 440
Substitute x = - 4 into the product
= (1353 × - 4) - 440
= - 5412 - 440
= - 5852
Your question can be reworded as
? X 3 = 20.
All you do is divide by 3 on both sides to isolate the x. It basically looks like a magician makes the 3 disappear and then appear on the other side.
Tadah! We have mathmagically found the answer.
The answer is
in fraction form or
in decimal form.
