Answer:
B
Step-by-step explanation:
surface area is finding the area of each portion of the net and adding them all up together. all the triangles are congruent, so we can start by finding the area of one of them and multiplying that area by 4 (since there are 4 triangles in this net). the formula for the area of a triangle is 1/2 bh. this is (1/2)(5.95)(5.1) which equals approximately 15.17. 4 multiplied by this is 60.68. the area of the square is length multiplied by width, which is 26.01. 60.68+26.01=86.69, which is the closest to answer choice B.
2 1/2 the absolute value of a positive number is that number
2, 5, 2 i think.
sorry if it’s wrong!
The domain should be all numbers GREATER than or equal to 3.
-(5-3)² + (8) - (-2) - 3 [4 + (-1)²]
Remember to follow PEMDAS
Simplify
5 - 3 = 2
2² = 4
-4 + 8 - (-2) - 3[4 + (-1)²]
Note that two negatives = 1 positive. Simplify
4 + 2 - 3[4 + (-1)²]
-1² = -1 x -1 = 1
4 + 2 - 3(4 + 1)
4 + 2 - 3(5)
6 - 15
-9
-9 is your answer
hope this helps
