Why is -a² is always negative (a ≠ 0) and why is (-a)² is always positive?

$-a^2=(-1)\cdot a\cdot a$

Regardless of the sign of $a$ , we have $a\cdot a=a^2\ge0$ (never negative). But multiplying by -1 makes it negative.

On the other hand,

$(-a)^2=((-1)\cdot a)^2=(-1)^2\cdot a^2=1\cdot a^2=a^2$

which can never be negative for real $a$ .

Hey there!

So, what you would do is . . .

$360$ ÷ $4$ . . .

$90$ ÷ $8$ =11.5

$Area=\boxed{\boxed{11.5}}$

Answer:

x = $-\frac{3}{b}$

x = -1

Step-by-step explanation:

The given equation is,

-2(bx - 5) = 16

Dividing by (-2) on both sides of the equation,

$\frac{-2(bx-5)}{(-2)}=\frac{16}{(-2)}$

(bx - 5) = -8

By adding 5 on both the sides of the equation,

(bx - 5) + 5 = -8 + 5

bx = -3

Dividing by 'b' on both the sides of the equation,

$\frac{bx}{b}=\frac{-3}{b}$

x = $-\frac{3}{b}$

If b = 3,

x = $-\frac{3}{3}$

x = -1

You use the equation Final Velocity²= (Initial Velocity)² 2(Acceleration)(Distance). You plug in what you have 0²=22.4² X 2(-3.5)(D) and solve for D which is 71.68m or about 72m.
