a) 2 ft by 6 ft
b) 2 ft by 8 ft
c) 4 ft by 3 ft
d) 4 ft by 4 ft

Xto the second power plus 14x plus 48. what are the factors? we are doing factoring trinomials with a=1

This is so hard and it’s for a test

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.
