Let X be large frames and Y be small frames.
X+Y=23
15X+5Y=195 or 3X+Y=39

Thus 2x=16
so X=8
so Y=15

23 x 32 is the prime factorization for which one of these choices?

antoniya [11.8K]

<h2><u>Answer:</u></h2>

⟶ 2³ × 3² is the prime factorization for which one of these choices?

Let's check,

1) 6 = 3 × 2 [So, obviously not this choice]

2) 25 = 5 × 5 = 5² [Not this either]

3) 36 = 3 × 2 × 2 × 3 = 3² × 2² [Doesn't match with 2³ × 3²]

4) 72 = 2 × 2 × 2 × 3 × 3 = <u>2</u><u>³</u><u> </u><u>×</u><u> </u><u>3</u><u>²</u><u> </u>[Matches]

⟶ The answer is, choice <u>7</u><u>2</u><u>.</u>

Triangle F G H is shown with its exterior angles. Line H G extends past point G. Line G F extends past point F. Line F H extends

klasskru [66]

Answer:

^G=98°

Step-by-step explanation:

So you know that angle x and angle g summed up together make 180°.

^F+^H+^G= 180°

<=> 53°+45°+^G=180°

<=> ^G= 180°-98°=82°

180°-82°=98°
