Answer:O C
Step-by-step explanation:
X - 4 = 16
X. = 16 - 4
X. = 12
Our two binomials are (X-5)(X-7)
If we FOIL those two terms [x*x = x2; x*-7 = -7x; x*-5 = -5x; -5*-7 = 35] and combine the like terms, we're left with one of many quadratic function
Answer
x2-12x+35
Answer:
Jenna is correct.
Step-by-step explanation:
I will assume that is what you meant.
Jenna is correct .
The square root of 4 ( = 2) is rational but,
for example, 2 is a rational number but the square root of 2 is irrational. Try finding the square root of 2 on your calculator. Your answer will be something like 1.414213562 but that decimal fraction goes on without bounds. No calculator will ever have enough memory to store that number!!

Answer:
after 7 minutes
19,600 feet
Step-by-step explanation:
Here's the "pencil and paper" solution:
The two altitude equations are ...
y = 41300 -3100x
y = 2800x
They can be solved by setting the expressions for y equal to each other.
2800x = 41300 -3100x
5900x = 41300
x = 41300/5900 = 7
y = 2800·7 = 19600
The planes will both be at 19,600 feet after 7 minutes.
Answer:
x=40
Step-by-step explanation:
8(1/2x + 5) = 200
4x + 40 = 200
4x = 160
x = 40
