Answer: -2w^2 + 25w = 25 or -2w^2 + 25w - 25 = 0</h3>
================================================================
Explanation:
Refer to the diagram below. The width is w. We have two opposite and parallel sides equal to this. The other two parallel congruent sides are L = 25-2w meters long. We start with the total amount of fencing, and then subtract off the two width values, so 25-w-w = 25-2w.
The area of the rectangle is
Area = length*width
Area = L*W
Area = (25-2w)*w
Area = 25w - 2w^2
Area = -2w^2 + 25w
Set this equal to the desired area (25 square meters) to get
-2w^2 + 25w = 25
and we can subtract 25 from both sides to get everything on one side
-2w^2 + 25w - 25 = 0
side note: The two approximate solutions of this equation are w = 1.0961 and w = 11.4039 (use the quadratic formula or a graphing calculator to find this)
Answer:
n≥-5
Step-by-step explanation:
-3n+2≥-4n-3
add 4n on both sides
n+2≥-3
subtract 2 on both sides
n≥-5
This can be solved using a system of equations.

Subtract y from both sides.

Substitute:

Subtract 80 from both sides:

Divide both sides by 5:

Substitute.
Itz B because 10-2=8
It would be like this 2/10 (btw it's not division...is a fraction) simplified to 1/5
Answer:
A. Point D could be the image of B.
D is up and to the right of B, so yes. Select choice A
B. Point C could be the image of A.
C is below A, so no
C. Point E could be the image of C.
E is up and to the right from C so yes, Select choice C
D. Point D could be the image of A.
D is down and to the right of A so no.
E. Point E could be the image of B.
E is up and to the right of B so yes. Select choice E
F. Point C could be the image of E.
No C is down and to the left of E.
