Compare how many place values the 3's have.
The 3 in 302754 is in the 6th place value, while the 3 in 53891 is in the 4th place value. Each place value is 10 times the one below it. Since the first 3 is 2 place values ahead, 10*10=100 times.

add like-terms with polynomials (Khan Academy) had really good videos on specific examples
Answer:
3 gallons
Step-by-step explanation:
If two gallons of paint covers 800 square feet, 'x' gallons of paints will cover 1200square feet room where x is the number of gallons needed to paint the 1200 square feet room.
Mathematically,
2 gallons = 800sq.ft
x gallons = 1,200sq.ft
x × 800 = 2 × 1200
x = 2 × 1200/800
x = 3 gallons
Therefore Leah will need 3gallons of paint for 1200sq.ft room
Answer:
<h2>Leah is actually wrong, because those rectangles are similar.</h2>
Step-by-step explanation:
Remember that similarity is about having proportional sides and congruent angles. When we have congruent sides, then those rectangles are congruent not similar.
In this case, to find the similarity, Leah should compare bases and heights thorugh division, because the ratio between heights and the ratio between bases must be equal. So, let's divide.
As you can observe, both ratios are equal.
Therefore, those rectangles are congruent.
