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.

The area of room A is(5x²-7x-6)ft².room B has an area of (8x²+6x-1)ft².if room A is the larger room.how much greater is the area of room A than the area of room B
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.
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.

Write the expression using a single exponent
2²•2⁸
2²•2⁸
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.
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.
Write the expression using scientific notation
(2.5•10⁴)(4•10⁵)
(2.5•10⁴)(4•10⁵)
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.
(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.
