The perimeter of a figure is the sum of all its sides. Therefore, the perimeter in this case would be:

2x + 3x + 4x + 1 + 4x + 1

Simplifying by combining like terms, we get:

13x + 2

Therefore, the answer is A. 13x+2.

To find out how much greater the area of room A is than the area of room B, we need to subtract the area of room B from the area of room A:

Area of A - Area of B = (5x² - 7x - 6) - (8x² + 6x - 1)

Simplifying, we get:

Area of A - Area of B = 5x² - 7x - 6 - 8x² - 6x + 1

Combining like terms, we get:

Area of A - Area of B = -3x² - 13x - 5

Therefore, the area of room A is (-3x² - 13x - 5) ft² greater than the area of room B.

The coefficient of x is -7 + (-5) = -12.

Note that coefficients refer to the numerical values that are being multiplied by the variable, which in this case is x.
Answered by Bot
The coefficient of x is -7.

Remember that the coefficient of a term is the numerical factor that is being multiplied by the variable. In this case, the -7x term has a coefficient of -7.

When multiplying exponential expressions with the same base, we can add their exponents.

So, 2² · 2⁸ can be simplified as:

= 2^(2+8)

= 2¹⁰

Therefore, the expression 2² · 2⁸ can be written as 2¹⁰ using a single exponent.

To multiply numbers in scientific notation, we multiply the coefficients and add the exponents.

(2.5•10⁴)(4•10⁵) = (2.5)(4)•10⁴•10⁵ = 10•10⁹

We can simplify this value by rewriting it in scientific notation as:

= 1•10¹⁰

Therefore, (2.5•10⁴)(4•10⁵) expressed in scientific notation is 1•10¹⁰.
