Multiply (2 - 71)(-1 + 41)?<br> 26 + 151<br> -2 - 281<br> 26 + i<br> -30 + 151

Ivahew [28]

For this case we must simplify the following expression:

$(2-7i) (- 1 + 4i)$

Applying distributive property we have:

$(2) (- 1) + (2) (4i) + (- 7i) (- 1) + (- 7i) (4i) =$

We have to:

$+ * - = -\\- * - = +$

So:

$-2 + 8i + 7i-28i ^ 2 =$

We add similar terms:

$-2 + 15i-28i ^ 2 =$

By definition we have: $i ^ 2 = -1$

$-2 + 15i-28 (-1) =\\-2 + 15i + 28 =$

Different signs are subtracted and the sign of the major is placed:

$26 + 15i$

Answer:

$26 + 15i$

24 points!! What is the measure of angle B in the triangle?

mestny [16]

Sum of all the angles in a triangle is 180
so, 120 + x + x+16 = 180
136 + 2x = 180
2x = 180 - 136
x = 44/2
x = 22

Now, Angle B = x = 22

In short, Your Answer would be 22

Hope this helps!
