Answer: fifty-two hundredths
Step-by-step explanation:
3x + 22 is the equation that represents the perimeter of the triangle. 4x + 10 is the perimeter of the rectangle. Setting the two equal:

and collecting like terms:

We find that the perimeter of both shapes is equal to 11 units.
Answer:
B
Step-by-step explanation:
Slope is the same(x) therefore they are parallel
Answer:
Step-by-step explanation:
let x be the number
2(x+8)=-4x+4
2x+16=-4x+4
6x=-12
x=-2
1) 100 * 40 = 4000 (cm²) the area of rectangle
2) 40 * 30 * 1/2 = 600 (cm²) the area of triangle
3) 4000 + 600 = 4600 (cm²)
Answer: 4600 cm²
