Evaluate (2 a + b)^2/(3 b - 1) where a = -2 and b = 5:
(2 a + b)^2/(3 b - 1) = (5 - 2×2)^2/(3×5 - 1)
3×5 = 15:
(5 - 2×2)^2/(15 - 1)
| 1 | 5
- | | 1
| 1 | 4:
(5 - 2×2)^2/14
2 (-2) = -4:
(-4 + 5)^2/14
5 - 4 = 1:
1^2/14
1^2 = 1:
Answer: 1/14
Answer:
Since the two angles are across from each other that tells us that they are equal in length, so we want to set them equal to each other
3x+50=6x-10, Now we want to solve it like a normal equation, get x by itself
First add 10 to each side
3x+50+10=6x-10+10
3x+60=6x
Now we want to subtract 3x from each side
3x-3x+60=6x-3x
60=3x
Now divide both sides by 3
60/3=3x/3
20=x
x=20
Hope this helps ;)

At the end of 6 years
Step-by-step explanation:
$14,000 loan at an interest rate of 5.4% for 6 years.
Amount to be paid at the end of the six years is
A= p(1+r/n)^(nt)
P= $14000
r= 0.054
t = 6
n = 6*12 = 72
A= 14000(1+0.054/72)^(72*6)
A= 14000(1+ 0.00075)^(432)
A= 14000(1.00075)^(432)
A= 14000(1.38247941)
A= 19354.71
A= $19354.71
