Answer:

Perimeter: 52 Area: 181-16i?

Step-by-step explanation:

<u>Perimeter</u>

The formula for perimeter is 2l+2w, so you plug in the binomials they give you:

2(11-4i)+2(15+4i)

expand:

22-8i+30+8i

combine like terms (which cancels out 8i and -8i):

22+30=52

<u>Area</u>

"i" is not a real number and thus should not be part of the area here, meaning this answer as it is is wrong and I don't know how one would change that.

Here's what I did to get 181-16i, in any case:

The formula for area is l*w, so I plugged in the numbers:

(11-4i)(15+4i)

expanded:

165+44i-60i-16i*i

and combined like terms:

181-16i

*i is \sqrt{-1}, so i^{2}=-1 and -1*-16=16.

Write each statement as an algebraic expression. The sum of a number c and its square.
Nikitich [7]
A sum means that two numbers are added together. A square means that a number is raised to the second power.

The sum of a number c and its square can be written with this algebraic expression:

c + c^{2}

A trapezoid has an area of 975 square meters. The height of the trapezoid is 50 ​meters, and the length of the longer base is tw
denis23 [38]
Area of trapezoid(A) =(1/2) (b1 + b2)*h

b1= x   - shorter base
b2=2x  - longer base
A=975 m²
h=50 m

975 =(1/2) (x + 2x)*50
975 = 25*3x
975 = 75x
x=975/75 = 13 m

x= b1 = 13 m
b2=13*2=26 m

b1=13 m,
b2 = 26 m,
