Answer:
16 sq. units
Step-by-step explanation:
<u>The formula for the area of a triangle:</u>
<u>If base and height are known as:</u>
- b = 8 units and h = 4 units
<u>Then the area is:</u>
- A = 1/2*8*4 = 16 sq. units
Answer:
HIIIIIIIIIIII
Step-by-step explanation:
Answer:
74 feet and 6 feet
Step-by-step explanation:
Mentioned that
The Length of the dog park is = (8x + 2)............(i)
And,
The Width of the park is = (2x -12)..................(ii)
Perimeter = 160 feet
Now here we use the perimeter formula which is
Perimeter is
= 2 (length + width)
160 = 2 (8x + 2 + 2x - 12)
160 = 2 (10x - 10)
160 = 20x - 20
180 = 20x
x = 9
Now put the x value into the equation 1 and equaton 2
For the equaton 1, the length us
= 8x + 2
= 8(9) + 2
= 74 feet
And, the width is
= 2x - 12
= 2(9) - 12
= 18 - 12
= 6 feet
F(x)= (x+1)^2
f(-2)= ((-2)+1)^2
= (-1)^2
= 1
