Think of the point, P, where the lines intersect as the center of a circle. The four angles with vertex P add up to 360 degrees. The given angle and its paired vertical angle are both 30 degrees. So, the other two angles are also vertical angles with sum 300 degrees (so each of them is a 150 degree angle).
No B
lets say W is 5
C is saying 4x5+6 right?
so all 4 side are 5 and plus a random six
W is only equal to 2 sides so C and D are gone
A. 2 x 5 + 6 is saying
2 sides are 5 + 6 and then a missing side
but B is 2 x 5 + 12
B could also say 2 x 5 + 2 x 6
2 sides are 5 and then 6 side are 5
Your answer is B
So, The length is 8 cm longer than the width.
Area of a rectangle = l *w
48 cm^2 = l *w
l = w+8
48 cm^2 = w * w+8
48 = w^2 +8w
^ that's the equation that models it. Or any other one listed
-5 +25-10m ≥ 60
20-10m ≥60
-10m ≥40
m ≤ -4 note flip equality sign because diving by a negative number
5 (4n+5)-4 ≤ 101
20n +25-4 ≤101
20 n +21 ≤ 101
20n ≤ 80
n ≤ 4
3(4-5p) -4 ≥ -67
12 -15p-4 ≥ -67
8 -15p ≥ -67
-15p ≥ -75
p ≤ 15 also flipped sign
-3(5m+2). < 54
-15m -6 &It 54
-15 m &Lt 60
m < -4
( I don’t know what sign < means I am assuming less than ? Just put the appropriate sign )
