pls brainliest btw
 
        
             
        
        
        
Area of triangle=1/2(base×height)
360=1/2((4x-2)(7x+5))
720=(4x-2)(7x+5)
FOIL the binomial
720=28x^2+6x-10
Bring 720 to the other side
28x^2+6x-10-720=0
28x^2+6x-730=0
Factor 2 out 
2(14x^2+3x-365)=0
Factor 2(14x+73)(x-5)=0
x-5=0
x=5
It can't be 14x-73=0 because the length can't be negative.
You're welcome.
        
             
        
        
        
The answer is B. If you take the even root of a positive number, you'll get two solutions, a positive and a negative

2) A
3) B
4) D
5)A
6) D
7)  A
8) C
9) D
Step-by-step explanation:
1) -5 (-2) -6= 4
2) 3 coins plus c coins = 3 + c
3) x-2 =16, x = 18
4)  =-5. Clearing, z =  60
 =-5. Clearing, z =  60
5) x =13,4
6) 14=t-4. Clearing t = 58
 7) -30=j+50, clearing j=80
8) 2.8x=-9.24, clearing x=-3-3
9) 5.8=  . Clearing z=12.76
. Clearing z=12.76
