Answer:
A
Step-by-step explanation:
(2x^2 + 3x - 4) (x + 4)
FOIL.
2x^2 times x = 2x^3
3x times x is 3x^2
-4 times x = -4x
2x^2 times 4 = 8x^2
3x times 4 = 12 x
-4 times 4 = -16
Combine like terms to get 2x^3 + 11x^2 + 8x - 16.
In this problem, the x intercept is 3.5 because the line crosses through the x axis at the point (3.5,0)
Answer:
B
Step-by-step explanation:
2^2 x 2^3 = 2^5
2^5/2^4 = 2^1
Answer: 3rd option : Angle 2 and 7
Step-by-step explanation:
Alternate exterior angles are located on the outside of the parallel line on opposite sides.
Therefore, the alternate exetrior angles are 1 and 8 and 2 and 7.
Since there is no option for angle 1 and 8, the correct answer is the 3rd option --> Angle 2 and 7.
Answer:
Given the sets:
K = {2, 3, 5, 8} and L = {3, 5, 7}
To find the union of K and L i.e, 
Union set defined as the union (denoted by U) of a collection of sets is the set of all elements in the collection.
Therefore, union for the following sets is, {2,3,5,7,8}.
