Can someone please help me with this?

65 mm²

Step-by-step explanation:

Total surface area of the prism = area of all parts of the prism's net

✔️Area of rectangle 1 with the following dimensions:

L = 5.2 mm

W = 2.1 mm

Area = 5.2*2.1 = 10.92 mm²

✔️Area of rectangle 1 with the following dimensions:

L = 5.2 mm

W = 4.5 mm

Area = 5.2*4.5 = 23.4 mm²

✔️Area of rectangle 3 with the following dimensions:

L = 5.2 mm

W = 5 mm

Area = 5.2*5 = 26 mm²

✔️Area of the 2 traingles with the following dimensions:

b = 4.5 mm

h = 2.1 mm

Area = ½*bh

= ½*4.5*2.1

= 4.725 mm²

Total surface area = 10.92 + 23.4 + 26 + 4.725 = 65.045 ≈ 65 mm² (nearesth while number)

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
