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>

As you can see there are two triangles but it can be done calculating just for one. First we must understand how formula for area of triangle works.

A=\frac{1}{2}bh

Where b represents base (hypotenuse) and h as height of the triangle.

We know that:

b=13cm \\h=4cm

Using this data we fill the formula.

A=\frac{1}{2}\cdot13\cdot4=\frac{13\cdot4}{2}=13\cdot2=\boxed{26cm^2}

Hope this helps.

A student states that Figure JKLM is congruent to Figure PQRS. Determine if the student is correct or has made an error. ;D
lyudmila [28]

Answer:

Student has made an error

Step-by-step explanation:

If two figures are said to be congruent, this implies that area of both is same and both as exactly same or copy or each other.

But from the graph, it can be stated that height of figure JKLM is 4 units whereas that of other is 6 unit.

<em>Hence explained !</em>
