Answer:

The result is 19

Step-by-step explanation:

3^{2}  + (5-2)x4 - 6/3

Step 1: Parenthesizing (5-2)=3

3^{2}  + 3x4 - 6/3

Step 2: Exponentiation 3^{2}=9

9  + 3x4 - 6/3

Step 3: Multiplication and division 3x4=12 and 6/3=2

9  + 12 - 2

Step 4: Addition and subtraction 9+12=21, and 21-2=19

21-2

19

The operations are ordered from highest to lowest in the order:

1. Parenthesizing,

2. Factorial,

3. Exponentiation,

4. Multiplication and division,

5. Addition and subtraction.

Hope this helps!

Answer: 21

Step-by-step explanation:

To work this out you will need the help of BIDMAS:

1. Brackets

2. Indices

3. Division

4. Multiplication

5. Addition

6. Subtraction

You must work this out one after the other

First we must get rid of the brackets by multiplication since brackets are similiar to ×.

3^2 + (5-2) × 4 - 6/3

+ (5-2) =

+ × 5 + × -2 =

5-2

Since + is infront we multiply it by the whole bracket and remember:

Positive (+) × or ÷ Positive(+) = Positive (+)

Negative (-) × or ÷ Negative (-) = Positive (+)

Positive (+) × or ÷ Negative (-) = Negative (-)

Negative (-) × or ÷ Positive (+) = Negative (-)

Then indices are next:

3^2 + (5-2) × 4 - 6/3

3^2 =

3×3 =

9

Then division:

- 6/3 =

2

It is explained above, and also if there is the minus symbol on both the number then the answer will end up with a plus, but if there is a minus on only one number then the answer will have a minus.

But in this case since there is a minus in both the numbers, then the result would be 2.

So right now there is supposed to be this numbers:

9 + 2 × 4 + 2

So then we multiply;

+2 × 4

+8

Finally we add everything up:

9 + 2 + 8 + 2 = 21

So in the end the answer is 21.

Let a Δ b = (a+b)2+5. what is 1 Δ - 4?
Arturiano [62]

It looks like ∆ is defined as

<em>a</em> ∆ <em>b</em> = (<em>a</em> + <em>b</em>)² + 5

If that's the case, then

1 ∆ (-4) = (1 + (-4))² + 5 = (-3)² + 5 = 9 + 5 = 14
