Answer:

-5x^2 - 25x + 18

Step-by-step explanation:

-3x ( x + 8 ) + x + 2 ( 9 - x - x^2 )  ( original equation )

-3x^2 - 24x + x + 18 - 2x - 2x^2   ( distribute )

-3x^2 - 2x^2 - 24x + x - 2x + 18   ( order them based on the variables . )

( -3x^2 - 2x^2 ) (- 24x + x - 2x ) ( + 18 )    ( just separated them not a part of solving !! )

-5x^2 - 25x + 18    ( solved , and the answer :) )

Solve A = a+b/2 for b
jeka94

Answer:

Step-by-step explanation:

I'm not sure if the right side is \frac{a + b}{2} or a + \frac{b}{2}, so I'll provide an answer for both:

A = \frac{a + b}{2}

2A = a + b

2A - a = b

A = a + \frac{b}{2}

A - a = \frac{b}{2}

2(A - a) = b

2A - 2a = b

A kilometre is about 5/8 mile. How many kilometres are in 2 3/4 miles?
Lapatulllka [165]

Answer:

To do this in my head: 60km = 40km+20km

So 40km/8km = 5

40 k is approximately 5x5miles = 25 miles

20k is half that or 12.5 miles

60 is about 25+12.5 miles

or 37.5 miles
