Vijay is building a new rectangular enclosure in his backyard for his chickens. he has 40 feet of fencing material and he wants the width of the enclosure to be 8 feet. if l is the length of the enclosure, and vijay used all of the fencing material, which equation best models the situation? a. l + 8 = 40 b. 2l + 8 = 40 c. 2(l + 8) = 40 d. 2l + 2(l + 8) = 40

The graph shows the distance kerri drives on a trip. what is kerri's speed?

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
