Answer:
![29+\sqrt{5}](https://tex.z-dn.net/?f=29%2B%5Csqrt%7B5%7D)
Step-by-step explanation:
Let
for simplicity. now our equation is
(2a+1)(3a-1)
now expand
2a*3a-2a+3a-1 = 6a^2+a-1
remember that ![\sqrt{5} = a](https://tex.z-dn.net/?f=%5Csqrt%7B5%7D%20%3D%20a)
thus we get![6\sqrt{5}^2+\sqrt{5}-1 = 6(5)-1+\sqrt{5}=30-1+\sqrt{5}=29+\sqrt{5}](https://tex.z-dn.net/?f=6%5Csqrt%7B5%7D%5E2%2B%5Csqrt%7B5%7D-1%20%3D%206%285%29-1%2B%5Csqrt%7B5%7D%3D30-1%2B%5Csqrt%7B5%7D%3D29%2B%5Csqrt%7B5%7D)
Answer:
x = 36
Step-by-step explanation:
The LCM (least common multiple) of 18 and 12 is 36.
Answer:
1.955
Step-by-step explanation:
$31.28 ÷ 16 = 1.955
X/5 > -2
Multiply 5 on both sides:
x > -10
Draw a graph and draw a line for x > -10
