Step-by-step explanation:
Answer:
(2 a - 5) (2 a + 5)
Step-by-step explanation:
Factor the following:
4 a^2 - 25
4 a^2 - 25 = (2 a)^2 - 5^2:
(2 a)^2 - 5^2
Factor the difference of two squares. (2 a)^2 - 5^2 = (2 a - 5) (2 a + 5):
Answer: (2 a - 5) (2 a + 5)
Answer:
∠A = 88°
∠B = 92°
∠C = 88°
∠D = 92°
Step-by-step explanation:
∠A + ∠B = 180°
(2x + 4) + (3x - 34) = 180
reduce:
5x - 30 = 180
5x = 210
x = 42
∠A = 2(42) + 4 = 88°
∠B = 3(42) -34 = 92°
∠C = ∠A = 88°
∠D = ∠B = 92°
