Answer:

When $p^2 - 4p$ is subtracted from $p^2 + p - 6$ , the result is $5p - 6$ . To get $p - 9$ , subtract $4p + 3$ from the result.

Step-by-step explanation:

✔️Subtracting $p^2 - 4p$ from $p^2 + p - 6$ :

$(p^2 + p - 6) - (p^2 - 4p)$

$p^2 + p - 6 - p^2 + 4p$ (Distributive property)

Collect like terms

$p^2 - p^2 + p + 4p - 6$

$5p - 6$

✔️Subtracting $p - 9$ from $5p - 6$ :

$(5p - 6) - (p - 9)$

$5p - 6 - p + 9$ (distributive property)

Add like terms

$4p + 3$

CAN SOMEONE JUST PLEASE ANSWER THIS ASAP FOR BRAINLIEST!!’

ANSWER

The three expressions are

$V = 2(9 - {b}^{3} )(9 + {b}^{3} )$

EXPLANATION

We were given the volume in cubic units to

$V = 162 - 2 {b}^{6}$

If we factor 2, we get,

$V = 2(81 - {b}^{6} )$

The expression in parenthesis is a difference of two squares. But you may not recognize it at first sight.

$V = 2( {9}^{2} - ({b}^{3})^{2} )$

This further gives us.

$V = (2)(9 - {b}^{3} )(9 + {b}^{3} )$

A rock concert promoter has scheduled an outdoor concert on July 4th. If it does not rain, the promoter will make $30,000. If it

Nastasia [14]

Answer:

(a) $12,000. It is reasonable since profit is positive

(b) $6,000

Step-by-step explanation:

(a) The promoter's expected profit is given by the product of his potential earnings by the probability that it does not rain, minus the product of his potential losses by the probability of rain:

$E(X) = \$30,000*(1-0.4)-\$15,000 *0.4\\E(X) = \$12,000$
