Ican't get it can anyone me i get most of it i just need number

Step-by-step explanation:

Should be 35 feet!!!

➷ Use Pythagoras' theorem:

a^2 = c^2 - b^2

Substitute the values in:

a^2 = 20^2 - 15^2

a^2 = 175

Square root it:

a = 13.22875656

In short, the house is 13.23 feet tall

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
