Answer:
- x = 0 or 1
- x = ±i/4
- x = -5 (twice)
Step-by-step explanation:
Factoring is aided by having the equations in standard form. The first step in each case is to put the equations in that form. The zero product property tells you that a product is zero when a factor is zero. The solutions are the values of x that make the factors zero.
1. x^2 -x = 0
x(x -1) = 0 . . . . . x = 0 or 1
__
2. 16x^2 +1 = 0
This is the "difference of squares" ...
(4x)^2 - (i)^2 = 0
(4x -i)(4x +i) = 0 . . . . . x = -i/4 or i/4 (zeros are complex)
__
3. x^2 +10x +25 = 0
(x +5)(x +5) = 0 . . . . . x = -5 with multiplicity 2

Answer: 9 kilos total thats it
Step-by-step explanation: Leaving the store Fatima thinks,“Each bag of groceries seems asheavy as a watermelon!”UseFatima’s idea about theweight of thewatermelon to estimate the total weight of 7 bags.c.The grocer helps carry about 9 kilograms. Fatima carries the rest.Estimate how many kilograms ofgroceries Fatima carries.d.It takes Fatima 12 minutes to drive to the bank after she leaves the store and then 34 more minutesto drive home.How many minutes does Fatima drive after she leaves the store?
P(A)= 4+5+6= 15/2= 75%
P(B)= 6+4=10 5/10= 50%
P(C)= 5+4=9 6/9= 66.6%
