Is known that

(a + b)² = a² + 2.a.b + b²

So:

(x + 4)² = x² + 2.x.4 + 4² = x² + 8x + 16

Answer: x^2 +8x +16
Explanation:
each term in the second bracket must be multiplied by each term in the first bracket
⇒(x +4)^2=(x+4)(x+4)⇒(x+4(x+4)
=x(x+4)+4(x+4)
=(x×x)+(x×4)+ (4×x)+(4×4)
=x2+4x+4x+16
=x^2+8x+16

That's all

Please help! I do not understand.

Because GH bisects FGI, FGH=HGI
2x+1=3x-9
x=10°
so the measure of HGI is 21°

What is 2/5 plus 1/3

leva [86]

First, you need to get the denominators (the bottom number) the same. The smallest number to get them to is 15.

So, what you need to do is take 2/5 and multiply the bottom by 3 to get 15, and since you did it to the bottom, you need to do it to the top too. So you would get, 6/15.

Then, for 1/3, take the bottom number and multiply it by 5. Then, since you did it to the bottom, do it to the top as well. You would get 5/15.

Then, you need to put them side by side. You don't add the bottom, so your denominator would remain 15, but your numerator (top) would get added.

 6 + 5 = 11
15 15 15
