0.0000000233</h2>
Step-by-step explanation:
Move the decimal point eight places to the left.
So you gotta use the AC method. What two numbers multiply to 4 and add to negative 5? It’s -4 and -1. Now you split up the -5 and then factor
I will show you how. 4x^2 -4x -1x +1
Now factor that —> 4x(x-1) -1 (x-1) see how there are two (x-1)?
We simplify it to (x-1)(4x-1) I took the two numbers of the outside and put them together. Now see that you multiply it out you get ur original unfactkred equation
Answer:
The correct answer is:
x ≤ 14 (b)
Step-by-step explanation:
first of all, let us find the other side of the rectangle using the limit of 46 as the highest perimeter:
Perimeter of a rectangle = 2(Length) + 2(width)
Let the length = x inches
let the width = 9 inches
Perimeter = 2x + 2(9)
46 = 2x + 18
2x = 46 - 18
2x = 28
x = 28 ÷ 2
x = 14
Therefore, for the perimeter to be equal to 46 inches, the other side of the rectangle must be equal to 14 inches. Hence, for the perimeter to be at most 46 inches ( 46 inches or less):
x is less than or equal to 14 (x ≤ 14)
The x intercept(s) occur when f(x) = 0
so we have (x - 3)( x^2 - 25) = 0
So x - 3 = zero and x = therefore = 3.
The answer is the third choice 3
