Answer:
Perimeter of the picture and frame = 38.4inches
Area of the picture and frame = 92.16inches²
Step-by-step explanation:
A square frame is made up of 4 different pieces. The shape of each piece = Rectangle
The perimeter of the rectangle = 24
Perimeter of the rectangle = 24 inches
The perimeter of a rectangle = 2L + 2W
The Width of a Rectangle is always on her than the length hence.
24 = 2L + 2W
24 = 2( L + W)
24/2 = L + W
12 = L + W
Because the width is always longer than the length
W > L
Width of wooden frame = 4 × Length
Therefore;
4 × L = W
Which gives
L + W = 12 inches
4 × L + L = 12 inches
L×(4 + 1)
= 5L = 12 inches
L = 12/5 = 2.4 inches
W = 4 × L = 4 × 12/5
W = 48/5 = 9.6 inches
Side length of wooden frame, L =9.6
The perimeter of the picture frame = 4 × L= 4 × 9.6= 38.4 inches
The area of the picture frame = L²
= L × L
= 9.6 × 9.6 = 92.16inches².
X= -157 to get that first you need to get 4×88 - 4 = 34 -2x then you do 352 - 4 = 34 - 2x after that do 348 = 34 - 2x then right 2X = 34 - 348 then the last step you do is 2x = -134
Answer:
the smallest part is 2
Step-by-step explanation:
lets take x as the smallest part
then the largest part=3x
the middle sized part=2x
x+2x+3x=12
6x=12
x=12/6
x=2
therefore the smallest part is equal to 2
Answer:
-4
Step-by-step explanation:
-4 x 13 = -52
Hope that helps :)
Answer:
D = -1, -1, 2, 5
R = 0, 2, 3, 7
✅It is NOT A FUNCTION
Step-by-step explanation:
D (Domain) = input values (x-values)
D = -1, -1, 2, 5
R (Range) = output values
R = 0, 2, 3, 7
✅It is not a function because an x-value, -1, has two different y-values, 7 and 2, assigned to it.
