S = -2-4r. You can't simplify the expression past that.
Answer:
m∠7=34°
Step-by-step explanation:
m∠2=m∠8=146° because alternate interior angles are congruent.
m∠7=180-m∠8=34° because it is a linear pair.
We can use the partition to break the number 286
286 = 200 + 80 + 6
286 = 100 + 100 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 1 + 1 + 1 + 1 + 1 + 1
286 consists of 2 hundred, 8 tens, and 6 units
Perimeter is equalt to 2l+2w where l is the length and w is the width
or l+l+w+w
so if the perimeter is 14 feet
and the length is 4 feet
14= 4+4+r+r
14= 8+ 2r
6=2r
r=3
the length of one side is 3 feet
