Answer:
The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.
Answer:
3x² - 14x + 14
Step-by-step explanation:
Given
3(x - 2)² - 2(x - 1) ← expand (x - 2)² using FOIL
= 3(x² - 4x + 4) - 2(x - 1) ← distribute both parenthesis
= 3x² - 12x + 12 - 2x + 2 ← collect like terms
= 3x² - 14x + 14
8160 dived by 85 equals 96, 2880 divided by 30 equals 96, therefore she can make 96 necklaces
The two angles are vertical from each other, we know this because they are directly across from one another
