Let h = height
h square = 20 square + 5 square
h square = 400+ 25
So you square root both sides
h = root 425
h = 20.6155281
Answer:
gay.... for points
Step-by-step explanation:
Not A because that is addition, B is correct because the identity property of multiplication is multiplying something by 1,
The answer is here
let be L the length of each ramp
so the <span>the length of the entire dog walk, including both ramps is D, such that
</span>D=L + L + d, where d=12ft
L=hypotenus, and sin30° = 4.5ft x L so L= sin30° / 4.5= 1/2x 4.5=2.25ft
D=2.25ft+2.25ft +12ft=16.5ft
The statement below is sometimes true. An example of this is with 1 and 2. Their lowest common multiple is 2 and 1 times 2 is 2. So, that's correct. Another example of this is with 2 and 4. Their lowest common multiple is four and 2 times 4 is 2 so that's not always right.
