Pls i don't know where to put the pharenteses this is the equation

15 - 25 x 2.4 + 7 - 3 x 2= -16

{15 - {(25 x 2.4) + 7}}- (3 x 2) = -16

Step-by-step explanation:

15 - 25 x 2.4 + 7 - 3 x 2= -16 is the given equation.

Now by the rule of BODMAS:

here B = Bracket, O means Of,  D means Divide, M means Multiplication , A means Addition and S means Subtraction.

So, according to this order start putting brackets.

first operation is multiplication, second is addition and then subtraction.

⇒  15 - 25 x 2.4 + 7 - 3 x 2  = {15 - {(25 x 2.4) + 7}}- (3 x 2)

Hence, {15 - {(25 x 2.4) + 7}}- (3 x 2) = -16

B. 137.32 cm3

Step-by-step explanation:

So what we know is that

Height = 12

Diameter is 6 which would make the radius 3.

The current volume is 339.12

12cm × 1.12 = 12.44 (This is the new height.)

3cm × 1.12 = 3.36 9 (This is the new radius)

Volume of future can (V2) = πr²h = 3.14 × 3.36 ×3.36 × 13.44 = 476.43

Then you would subtract  476.43(new volume) - 339.12(old volume) = 137.31

That would round to 137.32 cm3.

So the answer is B. 137.32 cm3.
