The algebraic expression could be K=5+k
Answer:

Step-by-step explanation:
Zeros of a quadratic equation are -1 and 5.
Sum of zeros = -1 + 5 = 4
Product of zeros = (-1)(5) = -5
The quadratic equation will be :

So, the required quadratic equation is
.
The explanation is here. the rest of the questions must be do by yourself.
-8 and 4. The product, -8 x 4, would be -32 (just think 8 x 4 = 32, then add the negative sign). The quotient, -8 / 4, would be -2 (just think 8/4 would be 2, then add the negative sign).
1 1/5 can be written as 6/5
7 1/2 can be written as 15/2
Let X be the number of laps Kellyn wants to jog to meet her 7 1/2 mile goal:
6/5x = 15/2 Multiply both sides by (5/6), the inverse of 6/5
x = 15(5) / 2 ( 6)
x = 75 / 12
X = 25 / 4, or 6 and 1/4 laps
