Answer:
Missing Coefficient is -8
Step-by-step explanation:
We are given, _y² - [ -5y - y( -7y -9) ] - [ -y(15y + 4) ] = 0
We have to find missing value.
let missing value be a
ay² - [ -5y - y( -7y - 9) ] - [ -y(15y + 4) ] = 0
ay² - [ -5y + 7y² + 9y ] - [ -15y² - 4y ] = 0
ay² - [ 7y² + 4y ] + 15y² + 4y = 0
ay² - 7y² - 4y + 15y² + 4y = 0
ay² - 7y² + 15y² + 4y - 4y = 0
( a - 7 + 15 )y² = 0
RHS can be written as
( a - 7 + 15 )y² = 0.y²
Now comparing coefficient of both sides we get,
a - 7 + 15 = 0
a + 8 = 0
a = -8
Therefore, Missing Coefficient is -8
Answer:
Area = πr²
Area = 3.14* 6²
A = 3.14 * 36
A = 113.04
Now find the area of the other one.
Area = πr²
A = 3.14 * 0.75²
A = 1.76625
Step-by-step explanation:
b. right
c. obtuse
d. straight

You can write this as 2/40. 2 is the sales tax and 40 is the total price. First, find the decimal. Divide the numerator by the denominator to get the decimal. You will get 0.05. Now, multiply the decimal by 100 to get the percent or just move the decimal two places to the right. The final answer is 5%
Hope it helps :)
