Answer:

$\boxed{\sf \ \ \ x^2 + x -72 = 0 \ \ \ }$

Step-by-step explanation:

Hello,

We need to use the <u>distributive property</u> which means that for a, b and c real numbers a(b+c)=ab+ac

So here we can write

$x(x+1)=72\\ x*x+x*1=72\\ x^2 + x -72 = 0\\$

Phoenix [80]

Answer:

Step-by-step explanation:

b. p(10.5<x<11.2)= p(x<11.2)-p(x<10.5)

p(x<11.2)= (11.2-9.7)/1 = 1.5 = 0.9332

p(x<10.5)= (10.5-9.7)/1= .8= 0.7881

.9332-0.7881= .1451

c. 9.7-.253, 9.7+.253
