Answer:

Step-by-step explanation:
1) Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd.

2) Collect like terms.

3) Simplify.

Therefor, the answer is, 10x^3 - 26x^2 - 12x.
Pythagorean theorem: a^2 + b^2 = c^2
36^2 + b^2 = 85^2
1296 + b^2 = 7225
b^2 = 7225 - 1296
b^2 = 5926
b = square root of 5929
b = 77 inches long
450=50x this should be correct :)
Answer:
138
Step-by-step explanation:
c=5
d=4
6c^2-5d+8
substitute c & d
6(5)^2-5(4)+8
6(25)-20+8
150-20+8 = 138
