I know y is 120 but idk what x is
Answer:
Step-by-step explanation:
if you have one side =2/7
area = (2/7)^2=4/49 m^2
Answer:
80,000
Step-by-step explanation:
Since 8 is 4 spaces to the left, it’s in the 10,000’s range, making it 80,000
Answer:
28
Step-by-step explanation:
l = length
w = width
p = perimeter
w = w
l + l + w + w = p (adding all the rectangle's sides together gets us our perimeter)
l = 2w + 4 (four more than twice the width)
Substitute 2w + 4 for 'l' in the original equation
(2w + 4) + (2w + 4) + w + w = 80
Solve equation normally:
6w + 8 = 80
6w = 72
w = 72/6 = 12
(w = 12)
Length = 2w + 4
Substitute 12 for 'w':
2(12) + 4 = l
24 + 4 = l
28 = l
The length is 28
