When you add 20 and 29, you get 49. When you add 21 and 28, you get 49. You will realize that there's 5 pairs that result in a sum of 49. 5*49=245.
Answer:
4). 47 - 29i
Step-by-step explanation:
(5+√-36)*(1-√-49)=5*1 -5√-49+1*√-36 -√-36√-49 = 5-5*7i +6i-6i*7i=
=5-35i+6i-42(-1)=5+42-41i= 47 - 29i
Answer:
any number
Step-by-step explanation:
It is because all real numbers are solutions to this
Answer:
Possible dimensions are 16 × 4 inches and 32 × 2 inches.
Step-by-step explanation:
We are given that,
Area of the frame = 64 inch² = Length × Width
Now, we have that 64 can be factored as,
64 = 32 × 2
64 = 16 × 4
64 = 8 × 8
Since, the frame is in a rectangular shape. So, we reject the possibility of 8 × 8 inches frame.
Thus, the possible dimensions are,
Set 1: 16 × 4 inches
Set 2: 32 × 2 inches.
