What value of x will make the given triangles congruent?
Molodets [167]
Because you're trying to make them congruent, equal the two expressions to each other. 

So, for #10 you would equal them so it would look like this. 
2x+2=5x-19

Then you would just go ahead and simplify

2x+2=5x-19
-2x     -2x
---------------
2= 3x -19
+19    +19
---------------
21=3x
---  ----
3     3

x=7

This means that x should be 7. You can check this just by plugging it in

2x+2
2(7)+2 = 16

5x-19
5(7)-19= 16

Same with #11.

x+8=3x-14
-x     -x
--------------
8=2x-14
+14   +14
--------------
22=2x
---  ----
2     2

x=11

Check. 

x+8
11+8= 19

3x-14
3(11) - 14 = 19

Im doing my math homework and this question came up, and i dont know what to do. Can someone please help?
LUCKY_DIMON [66]
Data:
P = 5.300,00
A = 7.000,00
r = 9% = 0,09
n = 4
t = ?

We have the following compound interest formula:

A = P*(1+ \frac{r}{n})^{nt}
7000 = 5300*(1+ \frac{0.09}{4})^{4t}
7000 = 5300*(1+ 0.0225)^{4t}
7000 = 5300*(1.0225)^{4t}
(1.0225)^{4t} =  \frac{7000}{5300}
(1.0225)^{4t} = 1.32075
Now, take the natural logarithm of both sides:
ln(1.0225^{4t}) = ln(1.32075)
4*t*ln(1.0225) =  = ln(1.32075)
4*t =  \frac{ln(1.32075)}{ln(1.0225)}
4t = 12.50301769...
4t \approx 12.50302
t \approx  \frac{12.50302}{4}
\boxed{t \approx 3.1258years}
