The diameter of the planet Mercury is 4.87 x10^3 kilometers. The diameter of the planet Venus is
1.21 x 10^4 kilometers. The diameter of Earth is
1.28 x 10^4 kilometers. The diameter of Mars is
6.79 x 10^3 kilometers. Which planet has the
smallest diameter?

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
