Answer:

(x + 4) and (x - 1)

Step-by-step explanation:

x² + 3x - 4

You want to look for what numbers can be multiplied in order to get the 3rd number (the -4) that can also add/subtract to the middle number (the 3)

simply,

(4)(-1) = -4

(4) -1 = 3

to make sure you can also reverse it and if you get to the same thing that you started with it is correct.

Lorenzo bought 3 pounds of grapes at $2.50 per pound, a gallon of milk for $4.25, and 2 boxes of cereal that originally cost $4
11Alexandr11 [23.1K]

Answer:

 Total  = $49.05

Step-by-step explanation:

cost of grapes per pound = $ 2.50

she bought 3 pounds of grapes

so cost of  3 pounds of grapes = 3 × 2.50

                                           = 7.5

gallon of milk = 8.6 pound

so cost of 8.6 pound of milk = 8.6 × 4.25

                         = $36.55

$ 1.50  off means =$4 - $ 1.50 = $2.5

cost of 2 boxes of cereal = 2 × 2.5

                             = $ 5

Total = 7.5 + 36.55 + 5

 Total  = $49.05

spinniong a spiner that has 5 equal sections marked 1-5 and landng on an even number. What your answer im simplest form and find
BARSIC [14]
You would have a 40% chance or a 2/5 chance because 5 numbers 1 through 5 would be 1 2 3 4 5 so 2/5 of the numbers are even, but 40% would also be the answer because 20% of 5 is 1, and 40% of 5 is 2. So 2 out of 5 are even so your answer is you have a probability of 40% or 2/5 toland on an even number. Please mark brainliest if this helped
