60
70
Answer:
20
Step-by-step explanation:
Answer:
∠TRS and ∠VRW equal because they are opposed by the vertex
x+40 = 3x
x-3x=-40
-2x=-40
x= 40/2 = 20°
∠TRS = x+40 =20+40=60°
∠VRW = 3x= 20*3 =60°
Step-by-step explanation:
81y4 – 16x2, the difference of squares
81y4 – 72xy2 – 16x2, a perfect square trinomial
81y4 – 72xy2 – 16x216, the difference of squares
Consider the expression You can see that in both brackets are the same terms and , but signs are different. So you can use formula for the difference of squares:
According to this formula,
