Answer:

4th term is 274.4 cm

5th term is 192.08 cm

Step-by-step explanation:

Here, we want to get the 4th and 5th term

Let us get the common ratio;

That would be ;

392/560 = 560/800 = 0.7

The 4th term will be ar^3

= 800 * 0.7^3 = 274.4

The 5th term will be ar^4

= 800 * 0.7^4 = 192.08

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!

Geometry help plz question below

Similar triangles have proportional corresponding sides and congruent corresponding angles.

For similar triangles we write

ΔGHI ~ ΔJKL

In these similarity expressions, the order of the vertices is meaningful. Here it tells us that G and J are corresponding vertices, as are H and K, as well as I and L. So ∠G≅∠J, ∠H≅∠K and ∠I≅∠L.
