Answer:
294
Step-by-step explanation:
The distributive property for multiplication is as follows :
a(b+c) = ab + ac
We need to evaluate 6 times 49 i.e. 6(49).
We can write 49 as (50-1)
6(50-1) = 6(50+(-1))
Here, a = 6, b = 50 and c = -1
So,
6(50+(-1)) = 6(50) + 6(-1)
= 300-6
= 294
So, answer is 294. Option (A) is somehow correct.
If you would like to solve the equation 7 * x = 42, you can calculate this using the following step:
7 * x = 42 /7
x = 42 / 7
x = 6
The correct result would be A. x = 6.
Answer:
± sqrt(3)i = x
Step-by-step explanation:
0 = x^2 +3
Subtract 3 from each side
-3 =x^2 +3-3
-3 =x^2
Take the square root of each side
±sqrt(-3) = sqrt(x^2)
±sqrt(-3) = x
We can split sqrt(-3) into sqrt(3) sqrt(-1) and we know that the sqrt(-1) is i
± sqrt(3)sqrt(-1) = x
± sqrt(3)i = x
Answer: the answer is 4
Step-by-step explanation:
2/3 / 1/6
change the places of 1/6 to 6/1
2/3 / 6/1
the division sign changes to multiplication
2/3 * 6/1
cancel out the 3 and 6 to give
2/1 * 2/1
=4
