So you're gonna take add 1 to both sides and add aw to both sides also
y+1=2w+aw
then you factorize the w
y+1=w(2+a)
divide 2+a in both sides
y+1/2+a=w
the answer is
y+1/2+a=w
<span>f '(x) = [(-40x +11)(7x - 9) - 7(-4x +3)(5x + 1)]/(7x - 9)2</span>
<span>= [(-280x2<span> + 360x + 77x - 99) - 7(-20x</span>2<span> - 4x + 15x + 3)]/(7x - 9)</span>2</span>
<span>= [(-280x2<span> + 437x - 99) + (140x</span>2<span> + 28x - 105x - 21)]/(7x - 9)</span>2</span>
<span>= (-140x2<span> +360x - 120)/(7x - 9)</span><span>2
</span></span>
i think thats how you would solve it
hope this helps tho:)
Kiloliters.Hope I helped.
It’s solved by using the cosine rule
Gia already used 1/4. 3/4 divided by 5 = 3/20
