Answer:

Step-by-step explanation:

Hello, please consider the following.

a)

(2x-2)^2 - (x+4)^2 \\\\=(2x-2-(x+4))(2x-2+x+4)\\\\=(2x-2-x-4)(3x+2)\\\\=\boxed{(x-6)(3x+2)}

b)

(3x+4) (3x-4)\\\\=(3x)^2-4^2\\\\=\boxed{9x^2-16}

Thank you.

Kryger [21]

Answer:

£2112

Step-by-step explanation:

To find Gavin's share, sum the parts of the ratio, 4 + 1 = 5 parts

Divide the win by 5 to find the value of one part of the ratio.

£8800 ÷ 5 = £1760 ← value of 1 part of ratio, thus

4 parts = 4 × £1760 = £7040 ← Gavin's share

Now repeat the process with the ratio for his family

1 + 6 + 3 = 10 parts

£7040 ÷ 10 = £704 ← value of 1 part of the ratio, thus

6 × £704 = £4224 ← wife's share

3 × £704 = £2112 ← son's share

Difference = £4224 - £2112 = £2112

Thus his wife gets £2112 more than the son

Using complete sentences, write an indirect proof proving that if x=30, then 3/4x+5≠20 (3/4 being three over four)
WARRIOR [948]
<span>hypothesis :-
 if x=30, then 3/4x+5≠20
 let Q:- x=30 P:- 3/4x+5≠20
 we need to prove if Q then P (Q →P)
 
proof :-
lets assume 34x+5=20 is true
now x=30
 so
  3/4(30)+5=27.5 ≠20
which is a contradiction
