Answer:
Step-by-step explanation:
<u>Given expressions:</u>
- 2(x + 2)
- 5(x - 8)
- 4 + (x • 4)
- 8(9 - x)
<u>Three of them in the form of:</u>
<u>One of them in the form of:</u>
Number 3 doesn't belong
Cos-1 divided by (15/21) rounded to nearest tenth 44.4
width of the rectangle = b = x
length of the rectangle = l = 8 + 2x
Perimeter of the rectangle = 70cm
Also, perimeter of the rectangle = 2(l + b)
70 = 2[x + (8 + 2x)]
70 = 2(x + 8 + 2x)
70 = 2(3x + 8)
70 = 6x + 16
70 - 16 = 6x
54 = 6x
54/6 = x
9 = x
Therefore, b = x
b = 9cm
l = 8 + 2x
I = 8 + 2×9
I = 8 + 18
I = 26cm

Answer:
m=3
Step-by-step explanation:
rise/run or y/x
using the y coords/x coords
15-0/-3-(-8)
=15/-3+8
=15/5
