Answer:

40x^{2} - 147x - 216

Step-by-step explanation:

(5x - 24) (8x + 9)

First start with multiplying 5x to 8x and 9

40x^{2} +45x

then multiply -24 by 8x and 9

        -192 x  -216

40x^{2} +45x

        -192 x  -216

The parallelogram shown below has an area of 404040 units^2 2 squared.
TEA [102]

Question:

The parallelogram shown below has an area of 40 units squared.

Find the missing base.

Answer:

See Explanation Below

Step-by-step explanation:

The question is incomplete as the diagram which shows the dimension of the parallelogram is not attached.

However, I'll give a general explanation on how to get the base of the parallelogram. If you follow this explanation, you'll get the right answer regarding your question.

The area of a parallelogram is calculated as thus.

Area = Base * Height

Given that the area = 40 units²

Let's assume the height of the parallelogram is 10 unit.

All you need to do is to plug in these values in the formula above..

Area = Base * Height becomes

40 = Base * 10

Divide both sides by 10

40/10 = Base * 10/10

4 = Base

Hence, Base = 4 units

Or take for instance the height is 5 units.

You'll still follow the simple steps as it is above.

Area = Base * Height becomes

40 = Base * 5

Divide both sides by 5

40/5 = Base * 5/5

8 = Base

Hence, Base = 8 units

The manufacturers of cans of salted moxies nuts state that the ratio of peanuts to other is 5 to 3. If 360 peanuts are in a can,
Rina8888 [55]

Answer:216

Step-by-step explanation:

We let x to represent the number of other nuts

Peanut : other

5 : 3

360 : X

Then we cross multiply

5 × x = 360 × 3

5X = 1080

Divide bothside by 5

5X/5 = 1080/5

X = 216

Therefore the number of other nuts in the can is 216.
