I think its A not 100% sure its the only one that starts on -3 but i think it is hope i helped you out
Using factorization method;
x²+13x+40=0
x²+13+40
Find two numbers that you can add together to give the co-efficient of variable x. (I.e 13 for this question). Also, you'll find two numbers that you can multiply with each other to give you the whole number as an answer. (I.e 40 in this question). The two numbers must be the same (i.e the two numbers that will be added to give the co-efficient of x and the two numbers that will be multiplied to give the whole number must be the same two).
The two numbers are +5 and +8
The equation will therefore be = x²+5x+8x+40
You'll then factorize (I.e use a common factor of both values to bracket them)
x(x+5)+8(x+5)
(x+8)(x+5)
x is therefore (x+8=0) or (x+5=0)
x=(x=0-8) or (x=0-5)
x= -8 or x= -5
Answer:
Bud have eaten 2 pieces as Bud and Dotti have eaten exact same amount.
Step-by-step explanation:
We have been given Dotti and Bud bought two identical watermelons
Dotti cut her watermelon into 3 pieces and ate 2 of the pieces.
Bud cut watermelon into 9 pieces
But Dotti and Bud have eaten exact same amount of watermelon
That means if Dotti have eaten 2 pieces then Bud would also have eaten 2 pieces out of 9.
