Answer:
Distributive Property
Step-by-step explanation:
2(x+4) = 2x + 8
2x + 2(4) = 2x + 8
2x + 8 = 2x + 8
Henceforth, distributive property
Answer:
101
Step-by-step explanation:
Triangle has 180 degrees in total
x+42+37=180
x+79=180
x=101
R + R = 10
4/3 r³ π : 4/3 R³ π = 27 : 343
r ³ : R ³ = 27 : 343 / ∛
r : R = 3 : 7
3 R = 7 r
R = 7 r / 3
r + 7 r / 3 = 10 / · 3
3 r + 7 r = 30
10 r = 30
r = 30 : 10
r = 3
Answer: the radius of the smaller sphere is 3.
