Answer:
4b ≤ 24
Step-by-step explanation:
The perimeter of a shape is its length+width+length+width, or 2L+2W :).
So, in order to find the perimeter of Teresa's math book, she can add 2(28)+2(21).
Hope I helped! :)
For rational expressions, all real numbers can be used as inputs, except for those that make the denominator equal to 0 (since division by 0 is undefined).
Thus, the domain restrictions are values that turn the denominator into 0. Since you have (x + 2) (x - 1) as the denominator, then it means that:
For (x + 2), the value of x CANNOT be -2, as it will result into 0.
For (x - 1), the value of x CANNOT be 1 because their difference will have 0 as a result.
Therefore, the correct answers are:
b.) x = 1
c.) x = -2

Answer:
Step-by-step explanation:
C(3 , -2) & D (7, -8)
Distance =
≈ 7.2 units
So, when I calculated this equation, I got 64. My final conclusion is 75 since it’s closer to my answer. If I’m correct, could you give me brainliest too if you don’t mind?
