Answer:

$4x^2-12x+9$

Step-by-step explanation:

we have

$(2x-3)^2$

we know that

$(a-b)^2=a^2-2ab+b^2$

In this problem

$a=2x\\b=3$

substitute in the formula

$(2x-3)^2=(2x)^2-2(2x)(3)+(3)^2$

$(2x-3)^2=4x^2-12x+9$

Ok so for the first one it’s super simple I’m gonna do it as less complicated so it can help you :)

So first we need to convert the mixed number to an improper fraction

1 4/5 = 9/5

Now we need to reduce the numbers greatest common divisor which is 3

3/5 x 6

Now multiply the numbers

Your answer is 18/5 I hoped this help

Now for the second one

this one is a little more complicated and I don’t know how to make it sound easier so I’m gonna tell you the answer which is 580/21

The last one is the same steps we did for the first one which is 27/20

I hoped this helped you it is a little difficult but you’ll get the hang of it :)

Answer:

SA = 3.04m²

Step-by-step explanation:

SA = 2 x ( Length x Width + Width x Height + Length x Height )

SA = 2 x ( 0.4 x 1 + 0.4 x 0.8 + 1 x 0.8 )

SA = 2 x ( 0.4 + 0.32 +0.8)

SA = 2 x 1.52

SA = 3.04 m²

I wish this could help you !
