Answer:
4600
Step-by-step explanation:
STEP 1: Determine type of progression
Since d1 = d2, it is Arithmetic progression, with a common difference of 4
STEP 2: Evaluate the sum
Answer:
53760
Step-by-step explanation:
12000 x 2 = 24000
24000 x .20 = 4800 this is the amount he gave to each of his sons
4800 x 3 = 14400 this is the amount he gave to his sons in total
24000 + 14400 = 38400
38400 x .40 = 15360 this is how much he gave to his wife
15360 + 38400 = 53760
Answer:Set \displaystyle f\left(x\right)=0f(x)=0.
Step-by-step explanation:
Set \displaystyle f\left(x\right)=0f(x)=0.
If the polynomial function is not given in factored form:
Factor out any common monomial factors.
Factor any factorable binomials or trinomials.
Set each factor equal to zero and solve to find the \displaystyle x\text{-}x- intercepts.
Answer:
(x - 4)(x^2 + 7)
Step-by-step explanation:
x^2 is a factor of the first two terms: x^3 - 4x^2 = x^2(x - 4).
7 is a factor of the last two terms: 7(x - 4).
Note how (x - 4) is a factor of the entire four-term expression given above.
Then: x^3-4x^2+7x-28 = (x - 4)(x^2 + 7)
