A banner is made of a square and two congruent semicircles. The square has lengths of 6 feet. The side of the square is also the diameter of the semicircles. What is the total area of the banner? (use 3.14 for pi)

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

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.
