which of the following are reasonable answers for the product of two negatives and a positive? •20 •10 •-20 •-10

Answers

The product of two negatives and one positive will give you a negative number. Take the three numbers; -1, -1, and 1. There are two negatives and one positive. 
-1 x -1 x 1 = 1 x 1 = 1 = positive number
So the possible answers are the positive numbers:

20 and 10

Hope this helps :)

The correct answers are:

20 and 10.

Explanation:

Multiplying two negatives results in a positive product. Multiplying this positive product by another positive number will result in a positive answer. This means the only possible answers from our choices are the two positive ones, 20 and 10.

The problem is asking for the surface area of a cylinder.
The formula for surface area of a cylinder is A = 2πrh+2πr²
radius = 1.5
height = 4

A = 2π(1.5)(4)+2π(1.5)²
A ≈ 51.84 in²

One of the angles formed by two intersecting lines is 30 degrees. What are the measures of the other three angles? please help im stuck on this one :(

Answers

Answer:

30, 150, and 150

Step-by-step explanation:

If you have two intersecting lines, there are going to be four angles that will all sum 360 degrees. The opposite angles will be identical. So, if you have one of the angles and it is 30 degrees, the opposite angle will be of 30 degrees as well. That adds 60 degrees, meaning that the remaining two angles will sum 300 degrees, and as they will also be identical, each will be of 150 degrees.

Answers

We can see on the number line that the bracket is 4 units long,
and the label above it says that it's (-3x + 1) long.

-3x + 1 = 4

Subtract 1 from each side:        -3x = 3

Now divide each side by  -3 :     x = -1
|2-(-2)|=-3x+1\n\n-3x+1=|2+2|\n\n-3x+1=|4|\n\n-3x+1=4\ \ \ \ |subtract\ 1\ from\ boh\ sides\n\n-3x=3\ \ \ \ \ \ |divide\ both\ sides\ by\ (-3)\n\n\boxed{x=-1}
