A rectangle has a height of 7a27a^2 7a 2 7, a, squared and a width of a4+5a2+4a^4+5a^2+4 a 4 +5a 2 +4 a, start superscript, 4, end superscript, plus, 5, a, squared, plus, 4 .

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will

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.

answer: group b.
