Please explain this type of problem (1+2i)(1+3i)
zhuklara [117]

Answer:

-5(1-I) is the answer

Step-by-step explanation:

(1+2i)(1+3i)

1(1+3i)+2i(1+3i)

1+3i+2i+6i^2

As i^2=-1

1+5i+6(-1)

1-6+5i

-5+5i

Taking -5 as common

-5(1-i)

Someone help with this
timama [110]

Answer:

18% decrease

Step-by-step explanation:

  1. 7,500 - 6,125 = $1,375
  2. Set up a proportion: \frac{1375}{7500} = \frac{x}{100}  
  3. Cross multiply, then divide: 1375 × 100 = 137500, 137500 ÷ 7500 = 18 1/3
  4. 18 1/3% rounded = 18%
  5. It went down, so it is a decrease

I hope this helps!
