Answer:  B) 14 + 22i

<u>Step-by-step explanation:</u>

    (5 + 3i)(4 + 2i)

= 5(4 + 2i)   +    3i(4 + 2i)      <em>Multiplied using distributive property</em>

= 20 + 10i   +    12i + 6i²        <em>Distributed</em>

= 20 + 22i + 6i²                    <em>Added like terms</em>

= 20 + 22i + 6(-1)     <em>             i² = -1</em>

= 14 + 22i                             <em>Simplified</em>

Mercury orbits around the sun is 87 24/25 earth days. Venus orbits the sun in 224 7/10 earth days, and Mars orbits the sun in 68
pav-90 [236]

For this case we have the following mixed numbers:

87 \frac {24} {25}\\224 \frac {7} {10}\\686 \frac {49} {50}

We convert each mixed number into decimal:

Mercury orbits:87 \frac {24} {25} = \frac {25 * 87 + 24} {25} = \frac {2175 + 24} {25} = \frac {2199} {25} = 87.96

Venus orbits: 224 \frac {7} {10} = \frac {10 * 224 + 7} {10} = \frac {2240 + 7} {10} = \frac {2247} {10} = 224.7

Mars orbits: 686 \frac {49} {50} = \frac {50 * 686 + 49} {50} = \frac {34300 + 49} {50} = \frac {34349} {50} = 686.98

Answer:

Mercury orbits: 87.96

Venus orbits: 224.7

Mars orbits: 686.98

  • k = possible number of cupcakes
  1. Number of strawberry slices = 46
  • Number if strawberry slices on each cupcake = 2

The inequality:

2k ≤ 46
