What is the quotient: (3x2 + 4x – 15) ÷ (x + 3) ?
Ivan

Answer:

No, it is 3x-5 and r=0

Step-by-step explanation:

We can do it by long division method  the required quotient is 3x-5 and r=0

not 3x-1 , r=1

multiply the divisor with 3x  we will get 3x^2+9xto cancel out the first term of dividend

Now after solving we will get -5x-15

Now, multiply the divisor by -5 we will get -5x-15 which will cancel the entire dividend.

Which expressions are equivalent to 2 (three-fourths x + 7) minus 3 (one-half x minus 5)? Check all that apply.
SOVA2 [1]

Answer:

29

Step-by-step explanation:

2 [(3/4)x + 7] - 3 [(1/2)x -5)]

2(3/4)x + 2(7) - [ 3(1/2)x - 3(5)]

3/2x + 14 - [ 3/2x - 15 ]

3/2x + 14 - 3/2x + 15

3/2x - 3/2x + 14 + 15

= 29
