The perimeter is the total length of all sides of the shape.
It is 1 meter + 1 meter + 2 meter + 2 meter = 6 meters
1 meter = 100 centimeter
6(100) = 600 centimeter
Hope this helps! :)
Explain to me a little more.
Than I can help you out a little more,
Thanks
1. "the sum of -4x and 2 is 9"? -4x + 2 = 9
Answer:
A.-4x + 2 = 9
2. solve x - 6 = -18
x = -18 +6
x = -12
Answer is B.x = -12
3. solve 4x + 3 = 47
4x = 47 -3
4x = 44
x = 44/44 = 11
Answer is A.x = 11
4. solve 1/3x = 12
x= 12 / (1/3)
x = 12 * 3 = 36
Answer is C.x = 36
5. solve 3x + 3 = 21
3x = 21 -3
3x = 18
x = 18/3 = 6
Answer is B.x = 6
6. solve. 3/2x - 4 = 16
3/2x = 16 + 4
3/2x =20
x = 20 / (3/2)
x = 20 * 2/3
x = 40/3
A.x = 13 1/3
Answer is B.x = 13 1/3
Answer:
x = 12
Step-by-step explanation:
Answer:
is not proportional.
is proportional
2x + 3y = 7 is not proportional.
Step-by-step explanation:
.
This is an equation in the slope-intercept form and the y-intercept of the equation is (0,4).
Therefore, this equation does not pass through the origin.
So, the equation is not proportional.
This is also an equation in the slope-intercept form and the y-intercept of the equation is (0,0).
Therefore, this equation passes through the origin.
So, the equation is proportional.
2x + 3y = 7
⇒
This is also an equation in the slope-intercept form and the y-intercept of the equation is ().
Therefore, this equation does not pass through the origin.
So, the equation is not proportional.
