Answer:
7x²-3x
Step-by-step explanation:
What is the are of the shaded region. The inner square is a width of x and a length of x+7. The outer square is a length of 4x and a width of 2x + 1.
Area of a square = Length * Length
Area of the inner square = x (x+7)
Area of the inner square = x²+7x
Area of the outer square = 4x(2x+1)
Area of the outer square = 8x²+4x
Area of the shaded region = Area of outer square - Area of inner square
Area of the shaded region = (8x²+4x)-(x²+7x)
Area of the shaded region = 8x²+4x-x²-7x
Area of the shaded region = 7x²-3x
This gives the area of the shaded region
Answer:
D) -20/-5 because a negative divided by a negative is a positive.
Step-by-step explanation:
Answer:
<u>100 m</u>
Step-by-step explanation:
<u>Given</u> :
<u>#1) Finding the side length</u>
- Area = (side length)²
- ⇒ side length = √Area
- ⇒ side length = √625
- ⇒ side length = 25 m
<u>#2) Calculating perimeter</u>
- Perimeter = Total length of the sides of the shape
- Perimeter = 4 x side length [a square has 4 equal sides]
- ⇒ Perimeter = 4 x 25
- ⇒ Perimeter = <u>100 m</u>
When two linear equations have only one solution the two lines on a graph would intersect each other ( they would only touch in one spot).
