Answer:
or, x2-(2-15)x +30= 0
or, x2-2x-15x + 30= 0
or,x(x-2)-15(x-2)=0
or, (x-2) (x-15)=0
either, or,
x-2=0 x-15=0
x2-(10+3)x+30=0
x2-10x-3x+30=0
x(x-10)-3(x-10)=0
(x-10)(x-3)=0
x-10=0 x-3=0
x=10 x=3
therefore,x=10,3
15/7
Step-by-step explanation:
8/7 + 7/7 = 8+7 = 15
Therefore, the sum of 8/7 + 7/7 is equals to 15/7
6 (x - 5) = 4x + 20
6x - 30 = 4x + 20
6x - 4x = 20 + 30
2x = 50
x = 25
H=110
since LW=85,W=5,=85+5=90/200=110
