Answer:
5,8
Step-by-step explanation:
x-y=3
x+y=13
(x-y)(x+y)=3*13
x^2-y^2=39
x=8, y=5
5 & 8
x-y = 3 -> x = 3+y
x+y = 13 = 3+y+y -> 3+2*y = 13
2*y = 10 -> y = 5
-> x = 3+y = 8
work is pictured and shown
24 cm³
V = LWH = 2 × 3 × 4 cm³ = 24 cm³
1) Either or ∦ (only two possibilities)
2) Assume (one of two possibilities)
3) (if two parallel lines are cut by a transversal, the corresponding angles are congruent)
4) But is not congruent to (given)
5) So ∦ (only other possibility)
