Which expression is equivalent to 32 + 16?8(4 + 2)
8(24 + 8)
7(4 + 2)
7(24 + 8)

Answers

Hi there! We know that 32+16=48 so all we have to do is find a expression that equals 48. 8(4+2)=48. 8(24+8)=256. 7(4+2)=42. 7(24+8)=224. Therefore, the expression that is equivalent to 32+16 is 8(4+2).

The answer is the first expression 8(4 + 2 )

32 + 16 = 48 and so does the first expression

the total volume of a cube is 360 inches to the third power how do you write 2 different possible sets of diminsions for the cube

Answers

If it's really a cube, then it can have only one set of dimensions.
Actually, only one dimension ... the length of every edge is the
same number.

The volume of a cube is the cube of its edge length. So the
length of every edge is the cube root of its volume.

But the dimension can sometimes be written in different ways.

Volume = 360 inch³

Edge length = ∛(360 inch³)

      = ∛360 inches

      = 3 ∛(13 and 1/3) inches

      = 4 ∛5.625 inches

      = 5 ∛2.88    inches

    = 6 ∛(1 and 2/3) inches .

Well,

Since it's a cube, there will only be one real dimension, and that will be the cube root of 360.

$\sqrt[3]{360} = 2\sqrt[3]{45}\ inches$

The only way to write different dimensions is to write using different units.

12 in. = 1 ft.

$\frac{2\sqrt[3]{45}}{12} = \frac{\sqrt[3]{45}}{6}\ feet$

1/6p + (-4/5) is the equivalent expression. You have to add like terms, meaning constants are added to constants, variables are added to variables, etc. the result you get from adding like variables leaves you with 1/6p + (-4/5) or 1/6p - 4/5

-25 - 17(9 + 8) I keep getting different answers..

Answers

We must use the order of operations as expressed by the saying:

Please Excuse My Dear Aunt Sally

P = Parentheses
E = Exponent
M = Multiplication
D = Division
A = Addition
S = Subtraction

So, we start with the parentheses:

-25 -17(17)

Next, we complete the multiplication problem:

-25 -289

Now, we do the subtraction problem:

-314

Hope this helps!
