0.4 and 0.40 are equal. That zero on the hundredths place does not matter.

How can you drop two eggs the fewest amount of times, without them breaking? <br><br>Answer, please
valentinak56 [21]
Drop the egg from half way up the building. This divides the search space in half. If it breaks, start on the bottom floor and work your way up the top :) Hope it works

WILL GIVE BRAINLIEST
castortr0y [4]

3. f(-6) = 12+1 =13


 f(-2) = 4+1 = 5


f(0) =1


Range {1,5,13}


4.  f(-2) = (-2)^3+1 =-7


  f(-1) = (-1)^2 +1 =0


f(3) = (3)^3 +1 = 28


Range = {-7,0,28}


5.the sequence is arithmetic


d= -11+19 = 8


an = a1 + d(n-1)


an = -19 +8(n-1)


6.l =w+5


a =l*w


a(w) =(w+5) * w


a(w)= w^2 +5w


f(w) = w^2 +5w


f(8) = 8^2 +5(8)


f(8) = 64 +40


f(8) =104 in^2

Please need help with son's assignment . Please answer the following questions
qaws [65]

Answer:

A. Perimeter of the square = 5s + 2

B. Perimeter of the rectangle = 8s + 8

C. Sum of the perimeters if s = 5:  75

D. Different between the perimeters if s=7:  27

Step-by-step explanation:

This problem is asking you to use expressions to first calculate the perimeters of two figures with a variable expression, then calculating the exact value of the perimeters when given the value of the variable.  For A, the perimeter of a square is the sum of all four sides, since the sides of a square are all equal.  You can find the answer by taking the given expression (5s + 2/4) and multiplying by 4 which gives you 5x +2.  For B, the perimenter of a rectangle is found by again adding up all the sides, however in a rectangle the opposite sides are equal, so the widths and lengths are the same.  In this case, we can take each expression and multiply by 2 and then add them together:  2(s + 9) + 2(3s -5) = 2s + 18 + 6s -10 = 8s +8.  For C, when given the value of s = 5, we can then substitute this number for 's' in both expressions:  5(5) + 2 = 27 and 8(5) + 8 = 48; 27 + 48 = 75.  For D, when given the value of s = 7, we can then subsitute this number for 's': 5(7) + 2 = 37 and 8(7) + 8 = 64; 64 - 37 = 27.
