Answer:
Step-by-step explanation:
(5x+1)²>(2x+2)²+(4x)²
25x²+10x+1>4x²+8x+4+16x²
5x²+2x-3>0
5x²+5x-3x-3>0
5x(x+1)-3(x+1)>0
(x+1)(5x-3)>0
x+1=0,gives x=-1
5x-3=0,gives x=3/5
x >0(because 4x should be >0)
side is always positive.
so x>3/5
again 5x+1<2x+2+4x
5x-6x<2-1
-x<1
x>-1
x=all real values >3/5
Answer:
c. (x+4)(2x)•(x + 4)(3x)
Step-by-step explanation:
Answer:
6) f=45
7) r=57
Step-by-step explanation:
the angles of a triangle will always add up to 180 degrees. Therefore, for the first one the three inside angles have to be 30, 15, and 135. If 135 is the supplementary angle to f, 45 must be the degree of f.
Same idea for the second one. 180-143=37. so 37+86+r=180. solve for r to get 57.
Nearest tenth is the number right after the decimal. If the number to the right of it is 4 or lower leave it how it is, and if the number to the right of it is 5 or greater than round up one.
