Answer:
P = 6x³ + 12x² - 18x + 8
Step-by-step explanation:
Given that:
Length = 3x3+4x2−6x
Width = 2x2−3x+4
The length of fencing needed will be :
Perimeter of rectangle (P) = 2( Length + Width)
P = 2[ (3x3+4x2−6x) + (2x2−3x+4)]
P = 2 (3x³+ (4x² + 2x²) + (-6x - 3x) + 4)
P = 2(3x³ + 6x² - 9x + 4)
P = 6x³ + 12x² - 18x + 8
Answer:
4 minutes 30 seconds
Step-by-step explanation:
Given:
Erica can run 1/6 of a kilometer in one minute.
Her school is 3/4 of a kilometer away from her home.
Question asked:
How long would it take Erica to run home from school = ?
Solution:
As here distance is given and also speed is given, we will find time taken to run from home to school by using,


Therefore, it takes 4 minutes 30 seconds Erica to run home from school.
Answer:
The slope of parallel line m = -7 is an integer
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the parallel line
-7x-y = 2
we know that the slope of the two parallel lines are equal
m₁ = m₂
The given parallel line equation
- 7 x - y = 2
The slope-intercept form
y = - 7x -2
comparing
y = mx +C
slope of parallel line m = -7 is an integer
y- Intercept c = -2
