Answer:
x^2 -5x +14 = 10^(2x +4)
Step-by-step explanation:
The relationship is ...
log(a) = b ⇔ a = 10^b
__
Using this with a=x^2-5x+14 and b=2x+4, we have ...
x^2 -5x +14 = 10^(2x +4)
_____
<em>Additional comments</em>
In plain text, the exponent needs parentheses, because superscript formatting is not available to tell what is and isn't part of the exponent.
The base of "log" is assumed to be 10 in high school algebra. In the larger world, "log" is often used in place of "ln" to mean the logarithm to base 'e'.

The one solution is approximately x = −1.32505947996.
Answer:
The population will be 135000
5000 x 3 = 15000
Then you add 120000 with 15000
Answer:
3, 6, 9, 12, 15, 18, etc.
It would basically be counting up by 3's
Another way to put this pattern is +6, -3
for e.g.,
0 + 6 = 6
6 - 3 = 3
No matter what units you are exchanging to and from, the number of unit cubes will remain constant.
For example: If I had a cube who's side was 10 km long, the number of unit cubes would be the volume of the cube which in this case is 1000 km³. So there would be 1000 unit cubes. Then, if I changed the side from 10 km to 10 in, and find the volume, it would be 1000 in³, meaning there are 1000 unit cubes!
So the answer to your question is: The number of unit cubes remains constant
Answer:
3.728 cm²
90
Step-by-step explanation:
To built the envelope I am using a rectangular piece of material 28 m long and 12 m wide.
Out of this material, I have to cut patches that are 1/12 the length and 2/15 the width of the whole material.
So, the length of the patches is 
m and the width of the patches is 
m.
Therefore, the area of the patches is (1.6 × 2.33) = 3.728 m² each. (Answer)
Now, the area of the rectangular piece of material is (28 × 12) = 336 m²
Hence, 
≈ 90 such patches can be made out of the whole material. (Answer)
