Answer:
The answer to your question is a² + 9a + 20
Step-by-step explanation:
10a² + 3a + 25 - (9a² - 6a + 5)
- Remove parentheses changing the sign of the second polynomial
10a² + 3a + 25 - 9a² + 6a - 5
- Group like terms
(10a² - 9a²) + (3a + 6a) + (25 - 5)
- Simplify and result
a² + 9a + 20
Answer:
3x+5y+12=0
Step-by-step explanation:
This information is given in the question:
m=-3/5
x1=-4
y1=0
The formula for the equation of a line is:
y-y1=m (x-x1)
From this we can make a substitution
y-0=-3/5 (x--4)
Next simplify
y=-3/5 (x+4)
Multiply both sides of the equation by 5
5y=-3x-12
Make the right side of the equation equal to zero
3x+5y+12=0
This is the equation of the line in general form.
Answer:
11 feet, 26 feet, 29 feet
Step-by-step explanation:
(2x+4 middle) + (3x- 4 longest) + (x smallest )= 66
2x +3x +x +4 - 4= 6x
6x = 66
x= 66/6
x = 11
smallest = 11 feet
middle = 2(11) + 4 = 26 feet
longest = 3(11) -4 = 29 feet
X in less than or equal to 4.5. it is this because 32 is the least number of miles per gallon. 144/32=4.5.
