The answer is 4n-25
4 times n is 4 n
and 25 decreased or subtracted from the 4n
thus the answer is 4n-25
Answer:
B) Similarities
B) vestigal trait
A)DNA
Step-by-step explanation:
1.2 is less than 1.5
If you cancel out 1 from both numbers you're left with .2 and .5
Multiply both by 10 and get 2 and 5.
Obviously 2 is less than 5.
Answer:x=6
Step-by-step explanation: Remove the radical by raising each side to the index of the radical
30°, 70°, and 80°.
It is an acute-angled triangle.
Explanation:
The ratio of the measures of ∠s in Δ is 3:7:8.
So, let us suppose that the measures are, 3k, 7k, 8k.
Evidently, their sum is
180°.
3k+7k+8k=180
18k=180
k= 10
Hence, the measures are,
30°, 70°, and 80°.
As all the angles are acute, so is the triangle.
