Answer:
(x^2+11)(x^2-11)
Step-by-step explanation:
You didn't list the options, but it should be:
(x^2 + 11) (x^2 - 11)
We use this formula: a^2 - b^2 = (a + b) (a - b)

The area that can be covered with grass seed by Derek is 8/15 acres.
Time spent while applying grass seed to 2/5 acre = 3/4 hour
Or, 3/4 hour is needed to apply grass seed to 2/5 acre.
What is a unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
3/4 hour ≡ 2/5 acre
1-hour ≡ (2/5)/(3/4) acre
1-hour ≡
1-hour ≡ acre
So, Derek can cover acre per hour.
Hence, the area that can be covered with grass seed by Derek is 8/15 acres.
To get more about the unitary method visit:
(2/5) acre / (3/4) hour
= 2/5 × 4/3 = 8/15 acre / hour

+4x +4x
5x + 4x = 9x
9x + 10 = -17
-10 -10
-27
9x = -27 9x/9 = -27/9
x = -3
this is how you solve for x;
5x + 10 = -4x -17
5x + 4x + 10 = -4x +4x -17 (add 4x on both sides)
9x + 10 = -17
9x +10-10 = -17 -10 (subtract 10 on both sides)
9x = - 27 (next do the inverse operation of x)
x = -27 ÷ 9
x = -3

Answer:
Any equation of the line that is different from y=x is the solution to the problem.
Step-by-step explanation:
step 1
Find the slope of the line that passes through the points (1, 1) and (5, 5)
m=(5-1)/(5-1)=1
step 2
Find the equation of the line into slope point form
y-y1=m(x-x1)
we have m=1
(x1,y1)=(1,1)
substitute
y-1=(1)(x-1)
y=x-1+1
y=x
therefore
Any equation of the line that is different from y=x is the solution to the problem.
