Answer:
4x − 10
Step-by-step explanation:
The width of rectangle A is 2x+4 and the length of rectangle A is x-1. This makes the perimeter
2(2x+4)+2(x-1)
= 4x+8+2x-2
= 6x+6
The width of rectangle B is 3x+1 and the width of rectangle B is 2x-3. This makes the perimeter
2(3x+1)+2(2x-3)
= 6x+2+4x-6
= 10x-4
Subtracting Perimeter B - Perimeter A, we ahve
(10x-4)-(6x+6)
= 10x-4-6x-6
= 4x-10
Answer:
if I am not mistaken, it is an obtuse triangle.
Answer:
option B
option D
Step-by-step explanation:
1)
First we will remove radical sign as and then multiply the powers.
2)
The "power rule" tells us that to raise a power to a power, just multiply the exponents.

Answer:
Incorrect
Step-by-step explanation:
This is incorrect. In order to add two fractions that have unlike denominators, it is true that you first need to find a common denominator. When you change a fractions denominator you must also change it's numerator in proportion to the change in the denominator. For example, if you change the denominator in the fraction into a 4 then you are multiplying the denominator by 2, therefore you will also need to multiply the numerator by 2 which would give you a new fraction of
Answer: area of the outer part of the rug= 16 -x²
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Area of a square: Side²
Since the area of the rug including the inner square is:
Area of the rug = 4² =16 in²
And the area of the inner square is equal to:
Area if the inner square = x²
To obtain the area of the outer part of the rug we have to subtract the area of the inner square to the area of the rug.
Area of the outer part of the rug= 16 -x²
