Distributive property And Combinding like terms two side equation 1. 2x - 4 = -9 - 3x
2. 5x + 34 = -2(1 - 7x)
3. -18 - 6x = 6(1 + 3x)
4. 2(4x - 3) - 8 = 4 +2x
5. 3(5x + 5) = (2x + 1)
6. 2(x + 10) = 2(3x - 8)

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much

Which expression is rational? 6. , square root two, square root 14, square root 49

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.
