Greatest common factor of 18 and 24 is 6.

6 because they both can have 6 divided into them.

Answer:

A = 139.5 cm^2

Step-by-step explanation:

Ok, let's break it down into pieces. First let's find the area of the main rectangle. We know that the area of a rectangle is as follows:

A = L x W

A = 9 x 12

A = 108 cm^2

Now we need to find the area of the two triangles. There are two ways to approach this. If you can visualize that you can flip the first triangle and slide it against the second, it becomes a rectangle. Then you can simply use the same formula as before with modified numbers.

L = 7 (height of the triangle

W = 4.5 (base of the triangle (half of 9))

A (both triangles) = 7 x 4.5

A (both triangles) = 31.5 cm^2

If you can't quite figure out how to visualize that, you can simply treat them as two independent right triangles. The formula for the area of a right triangle is as follows:

A = (1/2)b x h

b = 4.5

h = 7

A (first triangle) = (1/2)4.5 x 7

A (first triangle) = 15.75 cm^2

The area of the second triangle is identical

A (second triangle) = 15.75 cm^2

The area of the two triangles added together is

A (both triangles) = A (first triangle) + A (second triangle)

A (both triangles) = 31.5 cm^2

As you can see we got the same answer both ways. Now we just have to add the area of the two triangles to the area of the rectangle

A = 108 + 31.5

A = 139.5 cm^2

Over what interval is the function in this graph decreasing

posledela

C)

you look at were the graph starts to decrease then look at the X-VALUE not the y-value

the x-val at the start of the decrease is -3 and at the end of it it is 2 therefor -3 $\leq$ x $\leq$ 2

I WILL GIVE A BRANLIEST!<br>What is the graph of the functions?<br> y=2*2^x<br> y=-2*5^x

tekilochka [14]

For this case what you should know is that both functions are of the potential type.
We have then that
y = 2 * 2 ^ x
This function grows exponentially upwards.
y = -2 * 5 ^ x
This function grows exponentially downwards.

Set up and solve the following using dimensional analysis.

Softa [21]

1). Multiply (5400 inches) by (1 foot / 12 inch) then by (1 mile / 5280 foot).

(See explanation at the bottom)

= (5400 inch) x (1 foot / 12 inch) x (1 mile / 5280 foot)

= (5400 x 1 x 1 / 12 x 5280) (inch - foot - mile / inch - foot)

= 0.0852 mile

2). Multiply (16 week) by (7 day/week) then by (24 hour/day)
then by (60 minute/hour) then by (60 sec/minute).

3). Multiply (54 yards) by (3 foot/yard) then by (1 meter/3.28 foot)
and then by (1000 mm/meter)

4). Multiply (36 cm/second) by (3600 second/hour) then by (1 meter/100 cm)
then by (1 mile/1609.3 meter).

5). Look up how many grams in a pound ('P')
Look up how many mL in a gallon ('G')

Multiply (1.09 g/mL) by ( 1 pound/ P gram) then by (1 gallon/ G mL)

6). Multiply (32 foot/sec) by (1 meter / 3.28 foot) then by (60 sec/minute).

Each time I told you to multiply by something, it was always a fraction
where the numerator and denominator are equal, like (60 seconds/minute)
or (1 foot / 12 inch). Since the top and bottom of the fraction are equal, the
value of the fraction is ' 1 ' , and multiplying by it doesn't change the value,
it only changes the units ... that's what this whole exercise is about.
When you multiply, KEEP the units in the product, and then, after you multiply, you can 'cancel' units out of the top and bottom of the product.
Like if you have 'feet' on top and bottom, just cross them out. When you're done, if you did it correctly, the last unit you end up with will be the one you want.
