Answer:
-3/5
Step-by-step explanation:
tan = opp/adj using pathagorean the hypt is 5
cos = 3/5
tan is negative in quad 2 and 4
sin is positive in quad 1 and 2
so because tan is negative and sine is positive the cosine is negative
-3/5
Amaya = 4 pies
4 x 7 = 28 pieces
98-28 = 70
70 / 7 = 10
Cathy made 10 pies
(5x^4 – 3x^3 + 6x) – ( 3x^3 + 11x^2 – 8x)
Distribute the - to all terms in ( 3x^3 + 11x^2 – 8x)
5x^4-3x^3+6x-3x^3-11x^2+8x
rearrange and simplify common terms
5x^4-3x^3-3x^3+11x^2+6x-8x
5x^4-6x^3+11x^2-2x
Hi there!
You can use distributive property to solve this equation.
These are the list of terms you have to multiply :
a × a² = a³
a × -ab = -a²b
a × b² = ab²
b × a² = a²b
b × -ab = -ab²
b × b² = b³
add all of those terms...
a³ - a²b + ab² +a²b -ab² + b³
simplify by adding like terms... (- a²b + a²b , ab² - ab²)
a³ + b³
Hope this helped!! :)
