the perimeter is 68.8cm
Ok so because this is a rectangle the line directly across (paralell) is equal, so if one line is 16cm, the line parallel to that will also be 16. Then the formula for area is LxW we'd plug in the numbers we know to get 294.4
=16 x W
then we divide 16 by both sides to make it even to get 18.4cm=W. Now we just plug everything in to the perimeter by doing 16 x 2 + 18.4 x 2 to get
Step-by-step explanation:
12x + 3(x - 4) + 2x
17x-12

Answer:
The error in the students work is
y -(-8) + 8 = -6x + 12 + 8
subtracting a negative is adding
y+8
They should subtract 8 from each side instead of adding 8 to each side
Step-by-step explanation:
We can use point slope form since we are given a point and the slope
y-y1 = m( x-x1)
y--8 = -6(x-2)
y+8 = -6(x-2)
Distribute the -6
y+8 = -6x+12
Subtract 8 from each side
y+8-8 = -6x+12-8
y = -6x+4
The error in the students work is
y -(-8) + 8 = -6x + 12 + 8
subtracting a negative is adding
y+8
They should subtract 8 from each side instead of adding 8 to each side
Answer:
1. R
2. Match the year with the price. For example, 2006 should have a line directly on 15.
3. A (The first number on each row is the second number multiplied by 4)
4. C
5. A
