If the area of the rectangle shown below is given by the expression 3x2 + 7x – 6,

Mazyrski [523]

Answer:

Step-by-step explanation:

3x² + 7x - 6 = 3x² + 9x - 2x - 2*3

= 3x (x + 3) - 2(x +3)

= (3x - 2)(x + 3)

Area of the rectangle = 3x² + 7x - 6

length * width = 3x² + 7x - 6

length * (x + 3) = (3x -2)(x +3)

length = $\frac{(3x-2)(x+3)}{(x+3)}$

length = (3x - 2)

One satellite is scheduled to be launched from Cape Canaveral in Florida, and another launching is scheduled for Vandenberg Air

NeTakaya

Answer: $P\left ( A\right )=0.45$

$P\left ( B\right )=0.32$

Step-by-step explanation:

Given

$P\left ( A\cup B\right )=0.626$

$P\left ( A\cap B\right )=0.144$

and we know

$P\left ( A\cup B\right )=P\left ( A\right )+P\left ( B\right )-P\left ( A\cap B\right )$

$0.626=P\left ( A\right )+P\left ( B\right )-0.144$

$0.77=P\left ( A\right )+P\left ( B\right )$ -------1

as it is given

A and B are independent therefore

$P\left ( A\cap B\right )=P\left ( A\right )\cdot P\left ( B\right )$

$0.144=P\left ( A\right )\cdot P\left ( B\right )$

Substitute value of $P\left ( B\right )$ in 1

$0.77=P\left ( A\right )+\frac{0.144}{P\left ( A\right )}$

on solving $P\left ( A\right )=0.45$

$P\left ( B\right )=0.32$
