What is the factored form of 49x^2 – 56x + 16?
1 answer:
<span>the main formula is (a - b)² = a² -2ab + b²

w+2x=16 ⇒ w=16-2x
x+2w=14 x+2(16-2x)=14
x+32-4x=14
-3x=14-32
-3x=-18 /:(-3)
x=6
w=16-2x=16-2·6=16-12=4
2y+w=-6 ⇒ 2y+4=-6
2y=-6-4
2y=-10 /:2
y=-5
The value of the tenths place is 8
Answer:
(6x+10)°=(6x+10)°[vertically opposite angle]
now,
6x+10+10x+10=180°[being cointerior angle]
16x=180-20
x=160%16
x=10°
