What's the result for p=2(a+b) for b

1 answer:

4 0

p = 2 (a + b) Use the Distributive Property
p = 2a + 2b Subtract 2a from both sides
p - 2a = 2b Divide both sides by 2
$\frac{p - 2a}{2}$ = b Switch the sides to make it easier to read
b = <span> $\frac{p - 2a}{2}$ </span>

-16t^2+20t+65 Quadratic Formula

Shalnov [3]

The value of T is

$\frac{-5+\sqrt{285} }{8}$ OR $\frac{-5-\sqrt{285} }{8}$

Step-by-step explanation:

Assumption: find the values of t

1. Equation is $-16t^{2}$ +20t+65

2. Identify values of a, b and c

a = -16
b = 20
c = 65

3. Write the quadratic formula

t = $\frac{-b±\sqrt{b^{2}-4ac } }{2a}$

4. Substitute the values of a, b and c in the formula

t = $\frac{-b±\sqrt{b^{2}-4ac } }{2a}$

t = $\frac{-20±\sqrt{20^{2}-4(-16)(65) } }{2(-16}$

5. Solve to find the possible values of t

t = $\frac{-20±\sqrt{20^{2}-4(-16)(65) } }{2(-16}$

$\frac{-5+\sqrt{285} }{8}$ OR

$\frac{-5-\sqrt{285} }{8}$

When you roll a die, what kind of probability are you using

vfiekz [6]

It is a compound event with independent probability, which means that it can fall into any one of them (this happens if the die has not been tampered with). This means that one outcome does not affect the next outcome in anyway

hope this helps
