What multiplied by (x-4) would make x2+5x-36
Answer: x=sqrt10-2, x=-sqrt10-2
Step-by-step explanation: square root both sides of the equation.
x+2=sqrt10,-sqrt10
subtract 2 from both sides of the equation
x=sqrt10-2, -sqrt10-2
Answer:
Option B (35°).
Step-by-step explanation:
To solve this question, the trigonometric identity sin x = cos (90-x) is required. It can also be written as cos x = sin (90-x). It can be seen that this identity holds when the two angles are complementary i.e. they sum up to 90 degrees. Therefore, the answer can be determined by substituting all the options one by one in the identity cos x = sin (20+x). If x=30 degrees, then x+20=50 degrees. 30 and 50 are not complementary. If x=35 degrees, then x+20=55 degrees. 35 and 55 are complementary since their sum is 90 degrees. Therefore, B is the correct choice!!!
Answer:
False
Step-by-step explanation:
A subset is a set whose elements belong to another set
If B is a subset of A, B would contain elements of A
For example, A = {a, b, c} and if B is a subset of A , B = { a, b}
