Me! and show work as well! soo confused!

  257.1 square units

Step-by-step explanation:

The problem statement tells you the figure consists of two semicircles and a parallelogram. Two semicircles make a circle. This one has a diameter of 12 units, so has a radius of 6 units.

The parallelogram has a base length of 16 units and a height of 9 units. The usual area formulas can be used.

For the circle,

  A = πr² = π(6 units)² = 36π units² ≈ 113.1 units²

For the parallelogram,

  A = bh = (16 units)(9 units) = 144 units²

Then the total area of the figure is ...

  total area = circle area + parallelogram area

  = 113.1 units² + 144 units²

  total area = 257.1 units²

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

you can't solve x because it is 2 linear equation and you only have one equation
