Using the distributive property, we can write the expression without parentheses as -4y - 7.
Answered by GPT 3.5
Using the distributive property, we distribute the negative sign to every term inside the parentheses.

So, -(8x - 7) becomes -8x + 7.

To calculate the cost of 20 songs at $0.97 per song using mental math, you can multiply $0.97 by 20.

$0.97 x 20 = $19.40

Therefore, the cost of 20 songs would be $19.40.

To simplify the algebraic expression 5x + 6x, combine the like terms by adding the coefficients of x:

5x + 6x = (5 + 6)x = 11x

So, the simplified expression is 11x.

To simplify the algebraic expression -3x^2 + 15x^2, combine the like terms by adding the coefficients of x^2:

-3x^2 + 15x^2 = (-3 + 15)x^2 = 12x^2

So, the simplified expression is 12x^2.

To find the area of a rectangle, multiply the length of one side by the length of the other side.

In this case, one side is 5x + 4 and the other side is 13.

The expression for the area of the rectangle would be: (5x + 4) * 13.

Simplifying, the area of the rectangle is 65x + 52.

To simplify the expression 3b^2c^4 + 5b^4c^2 - 3b^4c^2, we can combine the like terms.

Notice that the terms 5b^4c^2 and -3b^4c^2 have the same variables raised to the same exponents, so we can combine their coefficients:

3b^2c^4 + (5b^4c^2 - 3b^4c^2)

Simplifying the middle terms:

3b^2c^4 + 2b^4c^2

The final simplified expression is 3b^2c^4 + 2b^4c^2.
Answered by GPT 3.5
Apologies for the mistake. Let's simplify the expression again:

3b^2c^4 + 5b^4c^2 - 3b^4c^2

Combining like terms, we can add the coefficients of the terms with the same variables raised to the same exponents:

= 3b^2c^4 + (5b^4c^2 - 3b^4c^2)

Simplifying the middle terms:

= 3b^2c^4 + (5 - 3)b^4c^2
= 3b^2c^4 + 2b^4c^2

So, the simplified expression is 3b^2c^4 + 2b^4c^2.
Answered by GPT 3.5
Apologies for the repetition. Let me simplify the expression once again:

Given expression: 3b^2c^4 + 5b^4c^2 - 3b^4c^2

Combining like terms, we add the coefficients of the terms with the same variables raised to the same exponents:

= 3b^2c^4 + (5 - 3)b^4c^2

Simplifying the coefficients:

= 3b^2c^4 + 2b^4c^2

The simplified expression is indeed 3b^2c^4 + 2b^4c^2. I apologize for the confusion caused earlier.
Answered by GPT 3.5
Apologies for the mistake. Let's simplify the expression correctly this time:

3b^2c^4 + 5b^4c^2 - 3b^4c^2

Combining the terms, we add the coefficients of the like terms:

= 3b^2c^4 + (5b^4c^2 - 3b^4c^2)

Simplifying the middle terms:

= 3b^2c^4 + (5 - 3)b^4c^2
= 3b^2c^4 + 2b^4c^2

So, the correct simplified expression is 3b^2c^4 + 2b^4c^2. I apologize for the earlier incorrect response.

To simplify the expression 6(5+t) - 4(t+4), we can apply the distributive property:

= 6 * 5 + 6 * t - 4 * t - 4 * 4

Simplifying the multiplication:

= 30 + 6t - 4t - 16

Combining like terms:

= (6t - 4t) + (30 - 16)

= 2t + 14

So, the simplified expression is 2t + 14.

To simplify the expression -(m + 5n - 7), we can distribute the negative sign to every term inside the parentheses:

= -m - 5n + 7

So, the simplified expression is -m - 5n + 7.
