Answer:

Step-by-step explanation:

area of top on triangle=1/2×4×3=6m²

area of four top triangles=6×4=24 m²

area of bottom square=4×4=16 m²

area of four side rectangles=4×(4×5)=80 m²

Total area= 24+16+80=120m²

The length of a rectangular prism is 4√3 units. The height is 3√6 units. If the volume is irrational, which could be the measure

Jet001 [13]

Volume = length * height * width
= 4 qrt3 + 3 sqrt6 * w
= 12 sqrt18 w

let w = 2 sqrt50 then volume = 2*12 * sqrt 18*50 = 24*30 so this is rational

let w = 4 sqt 12 the v = 48 sqrt12 * sqrt 18 = 48 sqrt30 which is irrational

C and D are rational
answer is B

How do you solve this question?

Lady bird [3.3K]

Answer:

$\large \boxed{\sf \ \ \ 2x-ln(1-x) \ \ \ }$

Step-by-step explanation:

Hello,

for any real x different from 1

$\dfrac{3-2x}{1-x}=\dfrac{2-2x+1}{1-x}\\\\=\dfrac{2(1-x)+1}{1-x}\\\\=2\dfrac{1-x}{1-x}+\dfrac{1}{1-x}\\\\=2+\dfrac{1}{1-x}$

if f(x)=2x

f'(x)=2

if g(x)=-ln(1-x)

$g'(x)=\dfrac{-1*-1}{1-x}=\dfrac{1}{1-x}$

So antiderivative of

$\dfrac{3-2x}{1-x}=2+\dfrac{1}{1-x}$

2x-ln(1-x)

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

Please answer :( If it takes 1/3 cup of flour to make 1/4 of a cake, how many cups of flour are needed to make a whole cake?

denis-greek [22]

Answer:

1 $\frac{1}{3}$

Step-by-step explanation:

1/4cake=1/3cup

Now times both sides by 4

$\frac{1}{4}$ x $\frac{4}{1}$ =1 cake

$\frac{1}{3}$ x $\frac{4}{1}$ = $\frac{4}{3}$ which equals 1 $\frac{1}{3}$
