The first answer is -15-20x.
The second answer is -42b-21.
Ask in the comments section if you want me to explain, other than combining like terms and using the distributive property. I hope this helps!
Answer:
You would write it as 3 * 10^6
Step-by-step explanation:
To figure this out, look at the decimal place: you got a huge number. 3,000,000. that's the decimal place, right at the far right side. Move the decimal place until you got a number less than 10, so until the number is 3. How ever many times you had to move the decimal place (in this case six times) is the number you put as the power. So the expression is:
3 * 10^6
Answer:
unsolvable
Step-by-step explanation:
because we have no data on what the decimals are worth. If I'm wrong please prove me wrong, but I'm pretty sure I'm right.
The answer is choice D) 4
(x/4) times 4 = x
You can think of it as
(1/4) times 4 = 1
Answer:
See explanation
Step-by-step explanation:
cos(θ)= 18/30 = 3/5
sin(θ)= 24/30 = 4/5
tan(θ)= 24/18 = 4/3
cos(ϕ)= 24/30 = 4/5
sin(ϕ)= 18/30 = 3/5
tan(ϕ)= 18/24 = 3/4
