Answer:
1. c^3 + 15c^2 + 75c + 125
2. 16x^4 - 96x^3y + 216x^2y^2 - 216xy^3 + 81y^4
Step-by-step explanation:
1. the binomial expansion will be the sum of the following terms
(3 C 0)c^3*5^0
(3 C 1)c^2*5^1
(3 C 2)c^1*5^2
(3 C 3)c^0*5^3
2. the binomial expansion will be the sum of the following terms
(4 C 0)(2x)^4(-3y)^0
(4 C 1)(2x)^3(-3y)^1
(4 C 2)(2x)^2(-3y)^2
(4 C 3)(2x)^1(-3y)^3
(4 C 4)(2x)^0(-3y)^4
hm
scalene
you can tell by the shape
(i hope this helps)
speed=distance/time taken
1.6
4.8/3= 1.6

the height of a triangle is A=(b·h)÷2
We know the area and base so replace: 72=(6×h)÷2
Solve:
72=(6×h)÷2
·2 ·2
144=6h
÷6 ÷6
h=24
24 yards
