Answer: 102.4 cm^2
Step-by-step explanation:
find the surface area of all of the rectangles
7.2(4)=28.8
7.2(2)=14.4
7.2(4)=28.8
7.2(2)=14.4
4(2)=8
4(2)=8
add
28.8+14.4+28.8+14.4+8+8=102.4

Answer:
The value of y is 36, and the value of z is 54.
Step-by-step explanation:
y has to be a number that can sit at 2y and then add itself to itself and become 3y.
40 is too high, and 35 is too low. Level it out, and you get 36.
Identify first the common difference of the arithmetic sequence by the following,
d = (a22 - a1) / 22 - 1
d = (-226 - 26) / 22 -1 = -12
Solving for the 31st term,
a31 = a1 + (n - 1)d
a 31 = 26 + (31 - 1)(-12)
a 31 = -334
Therefore, the answer is letter A. -334.
