Answer:
y=3x+2
Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
Perimeter of a square = 4*(side of the square)
28 = 4*(3x+1)
28 = 12x + 4
28- 4 = 12x
24 = 12x
x =2
E=6
f=8
H=12
h=?
a=?
a=5
h=12.25
Area=0.5*e*f+4*a*h*0.5=0.5*6*8+4*0.5*5*12.25=146.5
Answer:
x³ -x²-30x+72
Step-by-step explanation:
→ ( x - 3 ) ( x - 4 ) ( x + 6 )
[ expand and open brackets ]
→ ( x² -4x -3x + 12 ) ( x + 6 )
[ simplify ]
→ ( x² -7x + 12 ) ( x + 6 )
[ expand ]
→ x³ +6x² -7x² - 42x + 12x + 72
[ simplify/ final answer ]
→ x³ -x² -30x +72
