21 is the opposite of -21
Answer:
21 3/4 - 13 1/8 = 8 5/8 ft longer
Step-by-step explanation:
We subtract the blue rope from the green rope
21 3/4 - 13 1/8
We need to get a common denominator of 8
21 3/4*2/2 - 13 1/8
21 6/8 - 13 1/8
8 5/8

Answer:
x = 2
y = 9
Step-by-step explanation:
Opposite sides of a parallelogram are the same length. This relation is used to make equations with the given side lengths.
<u>Top and Bottom</u>
4x +20 = x +26
3x = 6 . . . . . . . . . . . subtract x+20 from both sides
x = 2 . . . . . . . . . divide by 3
<u>Left and Right</u>
7y = 6y + 9
y = 9 . . . . . . . . . subtract 6y from both sides
Answer:
A factor of f(x) is (x + 1).
Step-by-step explanation:
When we put x+1= 0 then we get the value x= -1
This value is then put into the function to find out whether it is a root or not. For a root to exist it must not have a remainder or the remainder must be zero.
Suppose the function is
F(x)= 2x³ - 42x - 40
f(-1)= 2(-1)³ - 42(-1) - 40
f(-1)= -2 + 42- 40
f(-1)= 0
This gives -1 as the root of the function.
