a cuboid's length is 9 cm, its height is 4 cm and its breadth is 6 cm. calculate the surface area.

any help is appreciated!!! :)​

Answer:

The answer is n = -14 .

Step-by-step explanation:

4 = 1/2(n + 22)

4 = 1/2n + 11

-7 = 1/2n

-7 / 1/2 = -14 = n

To check your work:

4 = 1/2(-14 + 22)

4 = 1/2(8)

4 = 4

Answer:

B

Step-by-step explanation:

4x - 3y = 9 → (1)

4x + y = 7 → (2)

Rearranging (1) in terms of x or y will involve using fractions, which we want to avoid if possible.

However, using equation (2) avoids introducing fractions.

In (2) subtract 4x from both sides

y = 7 - 4x → (3)

Then substitute y = 7 - 4x into (1) and proceed

Equivalent expressions are expressions that have equal values

The value of x is 25/6

From the question, the values of ac and ec are equivalent

So, we have:

8x - 14 = 2x + 11

Collect like terms

8x - 2x = 14 + 11

Evaluate the like terms

6x = 25

Divide both sides by 6

x = 25/6

Hence, the value of x is 25/6

Answer:

g[f(-2)] = 7

Step-by-step explanation:

f(x) = x^2

g(x) = 3x – 5

g[f(-2)]

First find f(-2) = (-2)^2 = 4

Then find g(4) = 3(3) -5 = 12-5 = 7

[tex]f(x)=x^2;g(x)=3x-5\\\\g[f(-2)]=3\times (f(-2))^2-5=3\times(-2)^2-5=3\times4-5=7[/tex]

Answer: 1 1/3 servings of pasta on the shelf.

Step-by-step explanation:

All you need to do is 8*1/6 because if there are 1/6 of a serving of pasta in each box and you have 8 boxes, then you need to multiply to find the number of servings.

8*1/6=1 1/3 or 1.(3)

(3) or any other number in parentheses next to a decimal means it's a repeating decimal, and it never ends.

Step-by-step explanation:

Convert from polar to rectangular

[tex]w=\sqrt{2}(cos(\frac{\pi}{4})+isin(\frac{\pi}{4}))\\\\w=\sqrt{2}(\frac{\sqrt{2}}{2}+\frac{\sqrt{2}}{2}i)\\ \\w=1+i[/tex]

Subtract the complex numbers

[tex]w-z=(1+i)-2i=1+i-2i=1-i[/tex]

Convert from rectangular (x,y) to polar (r,θ)

[tex]r=\sqrt{x^2+y^2}\\r=\sqrt{1^2+(-1)^2}\\r=\sqrt{1+1}\\r=\sqrt{2}\\\\\theta=tan^{-1}(\frac{y}{x})\\ \theta=tan^{-1}(\frac{-1}{1})\\ \theta=tan^{-1}(-1)\\\theta=\frac{3\pi}{4}\\ \\w-z=\sqrt{2}\biggr(cos(\frac{3\pi}{4})+isin(\frac{3\pi}{4})\biggr)[/tex]

The correct statement about Adi’s use of algebra tiles is She used the algebra tiles correctly.

Given

Adi used algebra tiles to represent the product

(-2x-2) (2x-1)

The number or expression results from the multiplication together of two or more numbers or expressions.

The correct way to find the product function is;

[tex]\rm =(-2x-2) (2x-1)\\\\=-2x(2x-1)-2(2x-1)\\\\= -4x^2+2x-4x+2\\\\= -4x^2+2x+2[/tex]

Hence, the correct statement about Adi’s use of algebra tiles is She used the algebra tiles correctly.

Answer:

26 degrees

Step-by-step explanation:

Triangle A:

So the triangle is 24 degrees and it is an isosceles triangle so the other 2 angles are equal. All the angles in a triangle add up to 180 degrees.

180-24=156 degrees

156 divided by 2 because of the 2 angles = 78 degrees

The angles in Triangle A are 78 degrees which means one corner of the Triangle X is 78 degrees as it is vertically opposite.

Triangle B:

B= 49 degrees and the triangle is isosceles as well. 49 x 2 for the other angle which would be the same is 98 degrees. We would then do

180 -98 = 82 degrees

This means the other angle in Triangle X is 82 degrees

Triangle X:

72 degrees is the top left angle and 82 degrees is the top right angle so you do 72+82= 154 degrees

180-154= 26 degrees

Answer:

300 cents or $3

Step-by-step explanation:

Let p be the cost of one pen and m be the cost of one mechanical pencil. We can use this to set up a system of equations:

4p+6m=1620 (convert $16.20 to cents by multiplying it by 100)

m=70

We can solve this using substitution (substitute 70 for m):

4p+6(70)=1620

4p+420=1620

Subtract 420 from both sides

4p=1200

Divide both sides by 4

p=300 cents or $3

Answer:

6a:10b

Step-by-step explanation:

Make both C's equal eachother which we could make 12

4x3=12 and 6x2=12

so we will have to do the same for the other numbers so when 4x3=12 then 2x3=6 and then do the same for 5b where 6x2=12 and 5x2=10

this would make the ratio 6a:12c:10b which would then make the ratio 6a:10b
