This equation simplified would be
-y(-5y+6)
Cosine is
which applies to a right triangle. I hope that helps you.
Answer:
C. 15
Step-by-step explanation:
Small triangle is similar to larger one so we can use the similarity ratio to solve the question:
CE/CA = DE/AB
4/12 = 5/AB cross multiply expressions
4AB = 60 divide both sides by 4
AB = 15
Answer: 
or 
Step-by-step explanation:
Add the exponent two to both sides. After adding -2 and 2 you get 0 and any number raised to the zero power is one. And 4 plus two is 6
=
Answer:
The equations 9x+8y=14100 and x = y+150 are in the simplest form.
Step-by-step explanation:
Given that:
Russian blue kitten costs $150 more than Manx kitten.
Cost of 9 blue kittens and 8 Manx kittens = $14100
Let,
x be the price of one Russian blue kitten.
y be the price of one Manx kitten.
According to given statement;
9x+8y=14100
x = y+150
Hence,
The equations 9x+8y=14100 and x = y+150 are in the simplest form.
