4x³ - 28x²

4x²(x - 7)

Step 2: Group last 2 terms together and factor

-1(x - 7)

densk [106]

Answer:

18.5

Step-by-step explanation:

First find the area of the two triangles.

1.5 * 1.5 = 2.25

Find the area of the two top rectangles: 2.5 * 1.7 * 2 = 8.5

Finally, find the area of the floor: 1.5 * 2.5 = 3.75

2.25 + 8.5 + 7.75 = 18.5

john currently has enough money to buy 45 books. If the cost of each book was 10 cents less.john could buy 5 more books. How muc
SVEN [57.7K]
Let the cost of one book= x cents
Let the money john have= y cents

According to the question,

45x=y                                               ...eq(1)
(45+5)(x-5)=y                                  
50(x-5)=y                                         
50x-250=y                                        ...eq(2)

On subtracting (1) from (2).
(50x-250)-45x=y-y
5x-250=0
x=250/5
x=50

Thus, cost of each book is 50 cents and john has 2250 cents.

Hope it helps.
Don't feel shy in saying thx if it helps.
