Answer:

Radius: 7.5 cm ; Diameter: 15 cm

Step-by-step explanation:

The radius of a circle is basically the middle "halfway" point and in this case, it has already been given, 7.5 cm. The diameter is the middle line of the circle and to find the diameter, you must multiply the radius by 2, which is essentially 7.5 cm*2, and this gives you a diameter of 15 cm.

Hope this helps! :D

Use the FOIL method to find the product. (x - 8)(x + 3)

Sliva [168]

Greetings and Happy Holidays!

FOIL stands for: First Outside Inside Last

FOIL is the order in which you would multiply (distributive property) the different terms:
$(x - 8)(x + 3)$

Multiply the First terms $(x)(x)$ :
$=x^2$

Multiply the Outside terms $(x)(3)$ :
$=x^2+3x$

Multiply the Inside terms $(-8)(x)$ :
$=x^2+3x-8x$

Multiply the Last terms $(-8)(3)$ :
$=x^2+3x-8x-24$

Simplify the expression:
$=x^2-5x-24$

The Answer Is:
$\boxed{=x^2-5x-24}$

I hope this helped!

The length of a rectangular garden is represented by 3x - 4 and the width is represented by 2x - 5 which of the following repres

galina1969 [7]

Answer: 6x^2 - 23x + 20

Step-by-step explanation:

To find the area of a rectangle you multiple length times width.

(3x-4)(2x-5)

Use foil to distribute the terms:

6x^2 -15x-8x+20

combine like terms

6x^2 - 23x + 20

I do not see a list of options so I can not tell you what letter answer this lines up with but this is the answer.
