The given expression gives the complex number:

N = 1 + 0i

<h3></h3><h3>How to add and subtract complex numbers?</h3>

Here we want to simplify the expression:

N = -4i + (1/4 - 5i) - (-3/4 + 8i) + 17i

Where i is the complex number, now we can just separate the terms with i and the terms without i.

N = -4i + (1/4 - 5i) - (-3/4 + 8i) + 17i

= (1/4 + 3/4) + (-4i - 5i - 8i + 17i)

= ( 1) + (-4 - 5 - 8 + 17)i

=  1  + 0i

That is the complex number that comes out of the given expression.

A tabletop in the shape of a trapezoid has an area of 5,350 square centimeters. Its longer base measures 135 centimeters, and th
borishaifa [10]

Answer:

54 cm

Step-by-step explanation:

Using the formula for the area of a trapezoid (area is the sum of the two bases times the height and then halved):

A = 1/2 (h) (b1 + b2)

5350 = 1/2 (h) (135 + 65)

5350 = 1/2 (h) (200)

5350 = h (100)

5350/100 = h

h = 53.5

h ≈ 54 cm

Plz help me with my home work and explain too plz asap
mrs_skeptik [129]
If you cut it into three pieces, it's easier to understand how to do it, as I show in the picture. when you are done splitting this into three parts you start multiplying. The side bases' digits are 31*23=713 and you need to do that twice, so 713+713=1,426. Next, you find the side-length for, and multiply, the middle base which is 23*19=437. Finally, you add all of that together 1,426+437=1,863.

Mary is three times older than seth is. if their ages total 76, how old is mary. Please answer ASAP
DedPeter [7]

Mary = 3x

Seth = X

If we know that Mary is three times older than Seth, we can set this up into an equation.

3x + x = 76

Now, we can simplify on the left side by adding the Xs together.

4x = 76

X = 19

Therefore, Seth is 19 years old and Mary is 57 years old.
