This is a formula if you need one. DON'T forget to cross-multiply
3/4 = x/12
Answer:
Step-by-step explanation:
x + 3y = 24.....multiply by -1
5x + 3y = 36
------------------
-x - 3y = -24 (result of multiplying by -1)
5x + 3y = 36
------------------add
4x = 12
x = 12/4
x = 3 <=======
x + 3y = 24
3 + 3y = 24
3y = 24 - 3
3y = 21
y = 21/3
y = 7 <========

Answer: Irrational</h3>
We cannot write sqrt(12) as a fraction of two whole numbers
Note how sqrt(12) = 3.464 and the decimal portion goes on forever without any known pattern (and it doesnt repeat either).
Compare this to something like sqrt(16) = 4 which can be written as a fraction 4/1, so sqrt(16) is rational
Answer:
B
Step-by-step explanation:
All we have to do is plug in the values! 1/2(4)(10+5) will give us the area. Now we simplify!
2(15) = A
30=A
Our answer is B!
X^2+20x+10 that's the answer
