First one is positive second one is negative third one is negative fourth one is positive and the last one is positive
"1 x 1" means whatever you want it to mean. There is nothing that says the operation "x" should be multiplication. There is nothing that says that "1" should even be a number. I could, just to be a regular A-hole, say that "1" is shorthand for a set of elements, and "x" is just a nice way of pairing "1" with itself, and I can call this a domain for a function I am about to define.
However, if we are being totally serious here, "x" means the operation of multiplication and "1" is a commonly understood concept referring to the idea of a single thing by itself. Multiplication is a short-cut for lengthy addition problems.
So 3x4 is a short cut for 3 + 3 + 3 + 3, or equivalently, 4 + 4 + 4. That's pretty much it. How many times do I add up 3? How many times to I add up 4?
So when you ask what is "1 x 1", you are really asking How many times do I add up 1? Well, you add up 1 just 1 time. That gives you 1.
Answer:
x=3
Step-by-step explanation:
6×sin(30)=3
__________
Right angle opposite is your hypotenuse
30° opposite it is your opposite

You're using Soh = Sin O/H but we dont have our opposite so we gotta times it instead with the side and sin(A) A would be your angle.
Answer:
A) True
Step-by-step explanation:
In an experiment that has the purpose of testing the efficacy of a procedure or drug, comparison is made against the efficacy of a placebo, a procedure or drug that is <em>intended to have no effect whatever</em>.
__
Famously, a placebo is often found to be nearly as effective (or even more effective) than the procedure or drug on trial. This effect is known as "the placebo effect."
Answer:
<u><em>2(2x² + 3)</em></u>
Step-by-step explanation:
<em>4x² + 5 + 1</em>
<em>= 4x² + 6</em>
<em>= 2(2x² + 3)</em>
