2f+10 can be written 2*f +2*5
We can see that 2 is common in both the terms thus we can factor it out.
2(f+5)
We can see that b is correct answer.
Ok so its (6,1) (4,-3) and (-2,-2)
Answer:
A. 7
Step-by-step explanation:
Since the triangle sides are not defined, therefore let the base side have the 12 unit and one of the slant side be 7 unit.
Therefore height of the triangle, h can gotten from the Pythagoras theorem as thus:
7² = (12/2)² + h²
49 = 36 + h²
h² = 49 - 36 = 13
h = √13
knowing the height of the triangle, we can apply same rule to the other unknown slant side, x as thus:
x² = (12/2)² + h²
x² = 36 + 13 = 49
x = √49
x = 7
Answer:
8
Step-by-step explanation:
5x+35 is because 5 times x would be 5x and 7 times 5 is 35
