Answer:
-2+3
Step-by-step explanation:
I'm assuming for g(x) you mean g(x) = x^2+3 for 
.
Going with that...
![\begin{aligned}f(g(x)) &= f\left( x^2+3 \right)~~~~~\text{plug $x^2+3$ in for $x$ in $f(x)$}\\[0.5em]&= 2\cdot ( x^2+3 )~~~~~\text{so $2x$ became $2(x^2+3)$}\\[0.5em]&= 2x^2+6\endaligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7Df%28g%28x%29%29%20%26%3D%20f%5Cleft%28%20x%5E2%2B3%20%5Cright%29~~~~~%5Ctext%7Bplug%20%24x%5E2%2B3%24%20in%20for%20%24x%24%20in%20%24f%28x%29%24%7D%5C%5C%5B0.5em%5D%26%3D%202%5Ccdot%20%28%20x%5E2%2B3%20%29~~~~~%5Ctext%7Bso%20%242x%24%20became%20%242%28x%5E2%2B3%29%24%7D%5C%5C%5B0.5em%5D%26%3D%202x%5E2%2B6%5Cendaligned%7D)
Just treat the enter g(x) function as a single input for f(x).
Answer:
C. 128 in²
Step-by-step explanation:
We know that the opposite sides of rectangles are congruent, so 8 = 2x. If we divide 8 by 2 and 2x by 2, we get x = 4.
- This means that the other side length, (3x + 4), equals 3(4) + 4 = 12 + 4 = 16 inches
Now, the area of a rectangle is l × w, where l = length and w = width. The dimensions of this rectangle are 8 and 16, so 8 × 16 = 128 in².
Hey there!
The answers would be
A. reproduction
B. temperature regulation
C. oxygen transportation
D. heat absorption
E. nutrient reproduction or ALL OF THE ABOVE
Water keeps all of your organs and cells functioning properly including the reproductive cells (egg, sperm) and reproductive organs (brain, ovaries, uterus, testes, thyroid). It also naturally flushes out toxins in the body. For men, semen production and semen volume can be reduced by not drinking enough water.
Water is intricately involved in numerous functions of the body including the transport of oxygen, nutrients and waste products into and out of the cells.
Water has a high heat capacity (an ability to absorb heat) because for water to increase in temperature, water molecules must be made to move faster within the water; doing this requires breaking hydrogen bonds (the H2 in H2O) and the breaking of hydrogen bonds absorbs heat.
Living organisms need water to survive. Other organisms require water to break down food molecules or generate energy during the respiration process. Water also helps many organisms regulate metabolism and dissolves compounds going into or out of the body.
Hope this helps!
Answer:
Step-by-step explanation:
Amount of water in tank 1 = amount of water in tank 2
30t +25 = -20t + 1000
Add 20t to both sides
30t + 20t + 25 = -20t + 20t + 1000
50t + 25 = 1000
Subtract 25 from both sides
50t + 25 - 25 = 1000 - 25
50t = 975
Divide both sides by 50
t = 975/50 = 39/2
t = 19 minutes 30 seconds
After 19 1/2 minutes both tanks will have 610 liters of water
