C the third one
Just plug in each answer givin into both equations untill both fit in.
In geometry, there is a theorem that states: The sum of any two sides of a triangle is greater than that of the third
Let's try to plug in and find if any two sides added together will be greater than the third:
a) 2 cm
3+5=8 and 8>2 [acceptable]
2+3=5 but 5=5 [not acceptable]
2+8=10 and 10>5 [acceptable]
b) 3 cm
3+3=6, 6>5 [good]
3+5=8, 8>3 [good]
.....
etc
We found that the answer has to be 2cm, because if we were to add a side of 2cm with 3cm, it would equal to the third side and the theorem states that the sum has to be greater
Hope this helped :) If so, leave a rating :)
Y = 4
3x + 4x = 43
3(9) + 4x = 43
27 + 4x = 43
4x = 43-27
4x = 16
16/4 = x
4=x
x=4
200+30 but its hard to understand what you are trying to say so please be more specific
Answer:
17 is C
18 is add
19 is C
Step-by-step explanation:
Question 18 is worded a little weird.
so. (x^2)(x^3) = x^5, so you should add the expotents when you are multiplying them.
