Answer:
a., b., e.
4x10^6 would be 4,000,000 so d. isn't correct.
40^6 equals 4,069,000,000 so c. isn't correct either.
Step-by-step explanation:

Answer:
1) x = 208 2) n = 28
Hope this helps! Have a great day!!
Step-by-step explanation:
1)
x - 72 = 136
+ 72 +72
x = 208
2)
n - 10 = 13 + 5
n - 10 = 18
+10 +10
n = 28
Answer:
The answer to your question is letter A
Step-by-step explanation:
Data
Vertex = (-5, -2)
Point = (-4, 2)
This is a vertical parabola the opens upwards.
The equation is
(x - h)² = 4p(y - k)
Substitution
(-4 + 5)² = 4p (2 + 2)
Simplification
1² = 4p(4)
1 = 16p
p = 1/16
Equation of the parabola
(x + 5)² = 4/16(y + 2)
x² + 10x + 25 = 1/4y + 1/2
Conclusion
The coefficient of the squared expression is 1
(100-9^2)/3
PEMDAS: parenthesis, exponents, multiply, divide, add, subtract
Lets' work on the parethesis first.
100-9^2
We can do the exponent first, 9^2=81, so 100-81=19
Then we divide and 19/3 is your final answer.
