Answer:
if i am incorrect please report my answer but im pretty sure that you are correct. have a nice day
Step-by-step explanation:
Okay so you split 9ab + 12ax - 6b - 8x
<span> into two 2-term polynomials </span>
+ 12ax + 9ab and - 6b - 8x
doesn't look that good to me so lest try other one :
9ab + 12ax and - 6b - 8x
looks good for now
<span> </span> Pull out from each binomial separately
9ab + 12ax = 3a • (3b + 4x)
- 6b - 8x = - 2 • (3b + 4x)
<span> </span> Add up to arrive at the desired factorization so now you have
<span> (3a - 2) • (3b + 4x)

Answer:
t = $4400 +/- $450
mean = $4400
standard deviation = $450
Step-by-step explanation:
Given;
Base salary b = $2000
Sales s = $8000 +/- $1500
Commission c = 30% sales = 0.3 × s
Total Salary t = base salary + commission = b + c
Commission c = 0.3×s = 0.3×($8000 +/-$1500)
c = $2400 +/- $450
Total salary t = b + c
Substituting the values;
t = $2000 + ($2400 +/- $450)
t = $4400 +/- $450
mean = $4400
standard deviation = $450
3x+8.5 =2.5x + 14.5
subtract 2.5x from each side
.5x + 8.5 = 14.5
subtract 8.5 from each side
.5x =6
multiply by 2
x =12
at 12 weeks they will be the same height
