X^2+3x-28
Synthetic division is very easy if u need elaboration on how to solve this problem just let me know and I’ll explain
Answer:
k - 2 = 4d - 8
d + 1 = 4d - 8
Step-by-step explanation:
Daniel's age = d
Kevin's age = k
Given that, k = d + 3 -------------- (1)
Two years ago, the age of Daniel = d - 2
Two years ago, the age of Kevin = k - 2
Since, two years ago, Kevin was 4 times as old as
Daniel, k - 2 = 4(d - 2)
Opening the bracket,
k - 2 = 4d - 8
Since the value of k is d + 3 (see (1))
d + 3 - 2 = 4d - 8
d + 1 = 4d - 8
(I am just giving the answer cause I LOVE Linear Equation )
1 + 8 = 4d - d
9 = 3d
9/3 = d
3 = d
Therefore, Daniel's present age is 3 and Kevin's present age = 6
Hope You understood
Thank You

Answer:
f(x) = ax^5 + bx^3 + cx^2 + 12.
Step-by-step explanation:
the degree is 5 so we will have a term like:
ax^5
it crosses the vertical axis at y = 12 so we will have a constant term equal to 12
the polynomial has 4 terms, and we already have two so we can make up two more but the exponent must be between 1 and 4
f(x) = ax^5 + bx^3 + cx^2 + 12.
it has 4 terms, f(0) = 12, then it intersects the y-axis at y = 12, and the maximum exponent is 5, then the degree of f(x) is 5
