F*2 = 4*2^3-2^2-5*2+7

Multiple: *(2) =
Power: 2 ^ 3 = 8
Multiple: 4 * 8 = 32
Power: 2 ^ 2 = 4
Subtract: 32 - 4 = 28
Multiple: 5 * 2 = 10
Subtract: 28 - 10 = 18
Add: 18 + 7 = 25= (25)

Therefore, your answer is 25.

O. Find the distance between P (10,-7) and Q (7,- 10). Leave your answer in radical form.

Answer:

$\sqrt{18}$ or $3\sqrt{2}$ units.

Step-by-step explanation:

To find the distance between two points, we can use the Distance Formula.

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Given:

P (10, -7) ⇒ x₁ = 10, y₁ = -7

Q (7, -10) ⇒ x₂ = 7, y₂ = -10

Substitute the given values into the formula and simplify.

$\\\implies d=\sqrt{\bold{(7-10)}^2+\bold{(-10-(-7))}^2}\\\\\implies d=\sqrt{\bold{(-3)}^2+\bold{(-10+7)}^2}\\\\\implies d=\sqrt{9+\bold{(-3)}^2}\\\\\implies d=\sqrt{\bold{9+9}}\\\\\implies d=\sqrt{\bold{18}}\\\\\implies d=\sqrt{\bold{9}\times2}\\\\\implies d=3\sqrt{2}$
