Write the perimeter of the figure as a polynomial. Simplify. Show your work.
2x, 3x,
4x+1, 4x+1,
A. 13x+2
B. 13x+1
C. 9x+1
D. 9x+2
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.
In the expression -7x-5x²+5,what is the coefficient of x
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.
-7x-5x²+5 what is the coefficient of x
7
5
-5
-7
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.
Write the expression using a single exponent
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.
