Prime factorising 392, we get,
392=2×2×2×7×7
=2
3
×7
2
.
We know, a perfect cube has multiples of 3 as powers of prime factors.
Here, number of 2's is 3 and number of 7's is 2.
Therefore, 392 is clearly not a perfect cube.
Here, we need to multiply another 7 to the factorization to make 392 a perfect cube.
Hence, the smallest number by which 392 must be multiplied to obtain a perfect cube is 7.
Answer:8
Step-by-step explanation:
(56+8 x 2) divided by 9
(56+16) divided by 9
72/9
8
Answer:
No
Step-by-step explanation:
Adding 8 groups of (-4) = -32
Dividing 8 and (-4) = -2
-2 doesn't equal -32

Answer:
Linear equation is
Step-by-step explanation:
We have,
Total monthly income (in dollars) = y
Number of times an app is opened = x
As, the advertiser pays $0.002 each time an app is opened.
So, the amount paid by the advertiser if an app is opened x times = 0.002x dollars.
Since, $30 per month is also paid by the advertiser.
Thus, total monthly income 'y' is given by,
Hence, the graph of the linear equation is given below.
