861 ÷3 show work for this problem please
TEA [102]
861 divided by 3: 

How many times does 3 go into 8? 2 x 3 = 6 
Subtract 6 from 8 to get a remainder of 2, and bring down 6 to get 26. 

How many times does 3 go into 26? 8 x 3 = 24
Subtract 24 from 26 to get a remainder of 2, and bring down 1 to get 21. 

How many times does 3 go into 21? EXACTLY 7 times. 7 x 3 = 21

Collect all numbers in bold to get…. 287!

Therefore, 861 divided by 3 = 287.

For questions 1 - 2, use the distributive property to find the product of the binomials.
igor_vitrenko [27]

Answer:

1).  2x^2-3x+20

2). 4x^2-14x+6

Step-by-step explanation:

1. (x-4)(2x+5)

FOIL:

(x)(2x)+5(x)-8(x)+(4)(5)

2x^2+5x-8x+20

=2x^2-3x+20

2. (4x-2)(x-3)

FOIL:

(4x)(x)-(3)(4x)-2(x)-2(-3)

4x^2-12x-2x+6

=4x^2-14x+6

tangare [24]
The square root is  \sqrt{\frac{144}{256}} = \frac{3}{4} Just square the top and bottom of the fraction. \sqrt{144} = 12 and \sqrt{256} = 16 so we have 12/16 and then we reduce to 3/4
