Answer:
(x + 1)(x + 7)
Step-by-step explanation:
Assuming you require the expression factored
x² + 8x + 7
Consider the factors of the constant term (+ 7) which sum to give the coefficient of the x- term (+ 8)
The factors are + 1 and + 7 , since
1 × 7 = 7 and 1 + 7 = 8 , then
x² + 8x + 7 = (x + 1)(x + 7) ← in factored form

I´m pretty sure it´s 2.(-3,6).
Step-by-step explanation:
Answer:
The z-value rounded to the nearest hundredth is -1.64
There is no enough evidence to reject the claim.
Step-by-step explanation:
A certain website claims that it averages 4.7 hours of downtime per month.
No. of samples = n = 17
Mean =
Standard deviation =
Formula:
Z =−1.64
Z critical at 90% is 1.65
Since Z calculated < Z critical
So, there is no enough evidence to reject the claim.
Answer:
3x - 6 = x + 9
2x - 6 = 9
2x = 15
x = 7.5

Answer:
381/1000
Step-by-step explanation:
0.381 = 381/1000 as a fraction
To convert the decimal 0.381 to a fraction, just follow these steps:
Step 1: Write down the number as a fraction of one:
0.381 = 0.381/1
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 3 numbers after the decimal point, we multiply both numerator and denominator by 1000. So,
0.381/1 = (0.381 × 1000)(1 × 1000)= 381/1000
