Answer:
Step-by-step explanation:
Store A price is 20x-7
store B price is 4(5x+7)
Where x represents the number of items.
Now, observe that the coefficient of both expressions is 20, because 4(5x+7)=20x+7
Remember that the coefficient of the x-variable is always the constant rate of change. Also, the given expressions can be expressed as linear functions
y=20x-7
y=20x+28
Observe that both Stores have already the same rate, which is 20.
Therefore, they have the same rate at any number of items dry cleaned.
What they have different is their initial condition, -7 and +7 respectively, but the rate is the same..
Schanzer (Gold Fever!) raids the annals of American history once again, emerging with a feisty tall tale inspired by the Davy Crockett almanacs published in the 19th century. Assuring readers that "every single word is true, unless it is false," she spins a rollicking yarn of how Crockett (who could "whip ten times his weight in wildcats and drink the Mississippi River dry") saves the world from a disastrous collision with Halley's Comet. Deep in the woods with his pet bear, Death Hug, Crockett is bent on wooing "purty" Sally Sugartree, unaware that the president has advertised for his help to reign in the comet. Once Crockett finds out he's needed, he's off "like a high-powered hurrycane," climbing to the top of a high mountain and leaping onto the comet. In the end, a triumphant Crockett gets both the girl and his coonskin cap (to cover what's left of his comet-singed hair). Schanzer's lickety-split pace and picaresque prose are equal parts swagger and sass, and her vibrant, color-drenched paintings extend the spirited tone. Careful attention to comic detail and visual echoes of the genre's hallmark exaggeration (Crockett, for instance, has the chiseled-jaw and popping muscles of a Disney hero) frame this zesty slice of Americana admirably. Ages 6-12. (Aug.)

Answer:
Step-by-step explanation:
Answer:
for circle in circle: 75π
circle in square: 64-16π
note that answers are in exact form, since I don't know how the answer should be written (exact or decimal etc.)
Step-by-step explanation:
for circle in circle, we see that smaller circle (white circle) has radius 5 and big circle has radius 10. therefore we can find area of shaded area by doing
area of big - area of small
10²π - 5²π = 100π - 25π = 75π
circle in square, applying the same method, we can do square-circle
since the circle is inscribed in the square, the circle's diameter is 8, so its radius is 4
8²-4²π = 64-16π

It's gonna be C and good luck!
