Answer:
Step-by-step explanation:
Solve for x over the real numbers:
x² + 14x + 38 = 0
Subtract 38 from both sides:
x² + 14x + 38 - 38 = 0 - 38
x² + 14x = -38
Add 49 to both sides:
x² + 14x + 49 = 49 - 38
x² + 14x + 49 = 11
Write the left hand side as a square:
x² + 7x + 7x + 49 = 11
x(x + 7) + 7(x + 7) = 11
(x + 7)(x + 7) = 11
(x + 7)² = 11
Take the square root of both sides:
Subtract 7 from both sides:
Answer:
The amount left after each friend got $46.
Step-by-step explanation:
Any time you see R1 in bus stop method division, it just means remainder. So dividing 93 dollars between 2 friends gives them both 46 dollars, with one left over!
Hope this helps :)
For these kinds of expressions use FOIL (first, outside, inside, last).
-2x • 9x = -18x^2
-2x • -3y = 6xy
8y • 9x = 72 xy
8y • -3y = -24y^2
Now combine them all:
-18x^2 + 78xy - 24y^2
Answer:
1.) Carries energy
Step-by-step explanation:
A good summary of an ATP molecule is a molecule that transfers energy between cells... meaning it carries energy from cell to cell. Furthermore, energy cannot be destroyed, and cannot be absorbed, only changed and transformed. This leaves us with two options, (1. Carries energy, and 4. None of the above). Since we already have a basic understanding of what an ATP molecule does, we can confidently determine that the correct answer is that an ATP molecule can best be described as carrying energy.
100-11.25-(4x15.25)=27.75 is the correct answer
