Answer:

4y-3x or -3x+4y

Step-by-step explanation:

first you have to distribute so you will do -1/3*9x and then -1/3*-12y

1. -1/3*9x=-3x

2. -1/3*-12y = 4y

then you have your answer 4y-3x or -3x+4y

Answer:

10 m.

Step-by-step explanation:

Volume of a pyramid is

V = 1/3Bh       B = area of base      h = height of pyramid

The base is a rectangle, so B = lw = 9(4) = 36

120 = 1/3(36)h = 12h

h = 10 m

Answer:

10 × 5 + 16 / 4 = 50 + 16 / 4 = 50 + 4 = 54

...........

Answer:

54.

Step-by-step explanation:

1. Replace the exponents and variables with their digits and then solve.

2. 10 x 5 = 50.

3. 4 x 4 = 16.

4. 16 / 4 = 4.

5. 50 + 4 = 54.

Answer:

5

Step-by-step explanation:

25 - 40 + 1

Answer:

The Correct Answer would be 5, Why? lets get into it.

Step-by-step explanation:

what we know is that Lauren bought soup for $40.

25% off 40 would be 10, 10-40=30 so Lauren´s soup now cost´s $30.

Now Lauren is at check out and tax is 10% of Lauren´s soup which is 10-30.

so 10% of 30 is 3 so Lauren´s soup originally costed $40 but +sale´s +tax now costs $33.

Answer:

72

Step-by-step explanation:

96 divided by 24 = 4

4 x 18 = 72

Answer: 128

Step-by-step explanation:

24/18 = x/96

x = 128

Answer:

1. 24/40, 32/40, 24/32 (This is in order from top to bottom)

2. 21.1

3. 4.1

Step-by-step explanation:

1. Here, we only have to focus on Angle X.

Let's label in the sides:

Opposite = YZ = 24

Adjacent = XY = 32

Hypotenuse = XZ = 40

SOHCAHTOA simply means:  You can memorise this through the acrostic poem of - Slap On Head Causes A Headache Take One Aspirin, but I remember it by Suck A Toe because that's what it sounds like.

Sin(x) = Opposite/Hypotenuse

Cos(x) = Adjacent/Hypotenuse

Tan(x) = Opposite/Adjacent

Sin(X) = 24/40

Cos(X) = 32/40

Tan(X) = 24/32

The question only asks to give the ratios by using / for a fraction, so we don't simplify it.

2. We are given the angle of 64°, the opposite length 19 and we have to work out x, which is the hypotenuse. We can use the sin function as we have our opposite length and we have to work out the hypotenuse.

Sin(64) = 19/x

xSin(64) = 19

x = 19/Sin(64)

x = 21.13943687

x = 21.1

3. We are given the angle of 70°, the hypotenuse 12 and we have to work out x, which is the adjacent side. We can use the cos function as we have to work out the adjacent side and we have our hypotenuse given to us.

Cos(70) = x/12

12Cos(70) = x  All we have to do here is multiply by 12!

x = 4.10424172

x = 4.1

First option

Step-by-step explanation:

Formula of perimeter =

Length + Length + Breadth + Breadth

So,

4x + 8 + 4x + 8 = 8x + 16

8x + 16 + 2x - 3 + 2x - 3 = 12x + 10

Answer:

400 m^2.

Step-by-step explanation:

The largest  area is obtained where the enclosure is a square.

I think that's the right answer because a square is a special form of a rectangle.

So the square would be 20 * 20  = 400 m^2.

Proof:

Let the  sides of the rectangle be x and y m long

The area A = xy.

Also the perimeter  2x + 2y = 80

x + y = 40

y = 40 - x.

So substituting for y in A = xy:-

A = x(40 - x)

A = 40x - x^2

For maximum value of A  we find the derivative and equate it to 0:

derivative A' =  40 - 2x = 0

2x = 40

x = 20.

So y = 40 - x

= 40 - 20

=20  

x and y are the same value so x = y.

Therefore for maximum area the rectangle is a square.

The largest area of rectangle will be 400 square meters.

Let us consider the length and breadth of rectangle is x and y respectively.

Perimeter of rectangle is given that 80 meters.

                                  [tex]2x+2y=80\\\\x+y=40\\\\y=40-x[/tex]

 Area of rectangle is,

                                        [tex]=x*y\\\\=x*(40-x)\\\\A=40x-x^{2}[/tex]

  For maximum area, differentiate Area with respect to x  and equate with zero.

                           [tex]\frac{dA}{dx} =\frac{d}{dx}(40x-x^{2} ) \\\\\frac{dA}{dx} =40-2x=0\\\\x=40/2=20m[/tex]

       So,    [tex]y=40-20=20m[/tex]

Area  = [tex]20*20=400m^{2}[/tex]

Thus, The largest area of rectangle will be 400 square meters.

The answer is C

[tex]3 {w}^{2} + 10w + 8[/tex]

Step-by-step explanation:

Let The width as (w) and lenth as(l)

Then l=3w

When the width increase by 2

Then the New width is w+2

And the lenth increase by 4

Then the New lenth is 3w+4

Then we can find the area
