Answer:
(4t − 3) (t − 6)
Step-by-step explanation:
Using AC method:
Given a quadratic ax² + bx + c, find factors of ac that add up to b. Divide those factors by a and reduce. The denominators become the coefficients and the numerators become the constants.
Here, a = 4, b = -27, and c = 18.
ac = 4 × 18 = 72
Factors of 72 that add up to -27: -3 and -24
Divide factors by a: -3/4 and -24/4
Reduce: -3/4 and -6/1
So the factored expression is:
(4t − 3) (t − 6)
Answer:
9 plants
Step-by-step explanation:
Since we are trying to find the number of plants that are shorter than 9 inches, we will look at the plants that are 2, 3, 4, 5, 6, 7, and 8 inches tall.
Each x counts as a plant
# of 2 inch plants: 1
# of 3 inch plants: 1
# of 4 inch plants: 4
# of 5 inch plants: 1
# of 6 inch plants: 1
# of 7 inch plants: 1
# of 8 inch plants: 0
Add up the number of plants:
1 + 1 + 4 + 1 + 1 + 1 + 0 = 9
Answer:
9 plants
Hope this helps!
I suppose that the value of y equals 2, seems how 4 times 2 what equal 8 and 8 times 2 would equal 16
Answer: 9
Step-by-step explanation:
27 divided by 3 is 9 so 9 is the constant variation
