14. The pattern is subtracting one number higher each time from each as it goes
Answer:
Area = 88 m²
Perimeter = 44 m
Step-by-step explanation:
✔️Area of the shape = area of the rectangle + area of the square
Area of the rectangle = L*W
L = 12 m
W = 6 m
Area of rectangle = 12*6 = 72 m²
Area of the square = s²
s = 4
Area of the square = 4² = 16 m²
Area of the shape = 72 + 16 = 88 m²
✔️Perimeter = sum of the sides surrounding the shape = 12 + 6 + 4 + 4 + 4 + 4 + 4 + 6 = 44 m
Answer:
3,4,5 forms a right triangle
1,2 ,9 does not form a triangle
Step-by-step explanation:
Three side lengths that will form a triangle
3,4,5
This is a Pythagorean triple. It forms a right triangle
3^2 +4^2 = 5^2
9+16=25
25=25
Three side lengths that will not form a triangle
1,2 9
The sum of the two smaller sides must be greater then the third
1+2 < 9 not greater
Answer:
Smallest integer=14
Step-by-step explanation:
(x+x+2+x+4+x+6)/4=17
(4x+12)/4=17
4x+12=68
4x=68-12
4x=56
x=56/4
x=14
numbers are: 14, 16, 18, 20
