Dmitry_Shevchenko [17]

Answer:

Step-by-step explanation:

$\frac{-3+7i}{-6-7i} \times \frac{-6+7i}{-6+7i} =\frac{18-21i-42i-49i^2}{(-6)^2-(7i)^2} \\=\frac{18-63i -49(-1)}{36-49i^2} \\=\frac{18+49-63 i}{36-49(-1)} \\=\frac{67-63i}{36+49} \\=\frac{67-63i}{85} \\=\frac{67}{85} +(\frac{-63}{85} )i\\$

$a=\frac{67}{85} \\b=\frac{-63}{85}$

Jason is covering an ottoman with fabric. The ottoman is in the shape of a rectangular prism that is 37 cm long, 21 wide, and 30

GrogVix [38]

Answer:

4,257 m²

Step-by-step explanation:

step 1

Find the lateral area of the rectangular prism (ottoman)

The lateral area is

LA=PH

where

P is the perimeter of the base

H is the height of the prism

Find the perimeter of the base P

P=2(37+21)=116 cm

we have H=30 cm

Find the lateral area

LA=116(30)=3,480 m²

step 2

Find the area of the top of the ottoman

B=37*21=777 m²

step 3

we know that

The fabric needed to cover the sides and top of the ottoman is equal to sum the lateral area plus the area of the top

3,480+777=4,257 m²
