3(5+7) is the problem you are looking at. To figure it out, you can use properties. On the right side of the equals sign, it shows a property you can use to do the problem. In this case, they are distributing.

How much area is left over

LenaWriter [7]

I won't tell you the answer but I'll tell you how to do it

first, find the area of the rectangle (lxw)

Next, find area of the triangle (BxHx.5)

Then, subtract the area of the rectangle to the area of the triangle

Find the zeros of the following

13 ) Go...

$f(x) = {x}^{2} - 2x$

$0 = {x}^{2} - 2x$

${x}^{2} - 2x = 0$

Factor x

$x(x - 2) = 0$

$x = 0 \: \: \: or \: \: \: x - 2 = 0$

$x = 0 \: \: \: \: or \: \: \: \: x = 2$

These are the zeroes.

14 ) Go...

$f(x) = {x}^{3} + 9x + 11x - 21$

$0 = {x}^{3} + 9 {x}^{2} + 11x - 21$

${x}^{3} + 9 {x}^{2} + 11x - 21 = 0$

$(x - 1)(x + 3)(x + 7) = 0$

$x - 1 = 0 \: \: or \: \: x + 3 = 0 \: \: or \: \: x + 7 = 0 \\$

$x = 1 \: \: \: or \: \: \: x = - 3 \: \: \: or \: \: \: x = - 7 \\$

These are the zeroes.

The area of a square 16/36sq foot how do u get side length of the sq?

aev [14]

We know that, the area of a square with side being s, is given by s², so if we here assume our side of square whose area is (16/36) sq. foot being s, so we will be having :

${:\implies \quad \sf s^{2}=\dfrac{16}{36}}$

${:\implies \quad \sf s=\pm \sqrt{\dfrac{16}{36}}}$

But, as length can never be -ve, so we will be taking only +ve length, and if we solve further for s, it will yield ;

${:\implies \quad \sf s=\sqrt{\dfrac{16}{36}}}$

${:\implies \quad \sf s=\dfrac{\sqrt{16}}{\sqrt{36}}}$

${:\implies \quad \sf s=\dfrac46}$

${:\implies \quad \boxed{\bf{s=\dfrac{4}{6}=\dfrac{2}{3}}}}$

Well, you might be thinking that (2/3)² willn't give (16/36) rather it will give (4/9), so for this, I'm telling that (2/3) ≈ 0.66666...7 and (4/6) ≈ 0.66666...7, so it's just the same thing and also, (16/36) and (4/9) are just too the same thing, dividing the numerator and denominator of (16/36) will just lead to (4/9) as same as (2/3)²
