Answer:

Step-by-step explanation:

((8 x 10) x 3) + ((9 x 8)/2) x2 = (80 x 3) + (72/2) x 2
= 240 + (36 x 2)
= 240 + 72
= 312

Sorry it’s small I could not get it in just zoom in

Hello!

Graphs A and D are reflected, not rotated, so they are not the answer.

Graph C is rotated 180°, so it is not the answer.

This leaves us with B as our final answer.

I hope this helps!

Alex

Answer:

x=2 and y=3

Step-by-step explanation:

y-2=x-1

or,x-y=-1.......(1)

again,

2x+1=y+2

or,2x-y=1.......(2)

now,

solving equations (1)&(2),we get,

x=2 and y=3

Abdul is creating a cushion that is 1 foot by 2 feet by 3 feet. He wants to find the least amount of fabric he will need to cove

netineya [11]

Answer:

The least amount of fabric are 22 square feet

Step-by-step explanation:

we know that

The surface area of a rectangular prism is given by the formula

$SA=2B+PH$

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

Let

L ---> the length pf the prism

W ---> the width of the prism

H ---> is the height of the prism

Let

$L=2\ ft\\W=3\ ft\\H=1\ ft$

Find the area of the base

$B=LW=(2)(3)=6\ ft^2$

Find the perimeter of the base

$P=2(L+W)=2(2+3)=10\ ft$

Find the surface area

$SA=2(6)+10(1)=22\ ft^2$

therefore

The least amount of fabric are 22 square feet
