Answer:

(2x+12)

Step-by-step explanation:

We can re-write (2x+8)+4 using the associative property of addition. The associative property states that you can move around the parenthesis in an addition problem.

We can write (2x+8)+4 as 2x+(8+4).

2x+(8+4) = 2x+12.

There are 30 students in Mrs. Taylor's kindergarten class. If there are twice as many students with blond hair as with blue eyes

weqwewe [10]

Answer:

Step-by-step explanation:

Let e represent the number of students with blue eyes. Then the number of students with blond hair is 2e. The total number of students is ...

3 + e + 2e -6 = 30

We subtracted 6 because the expressions e and 2e cause the 6 students with both blond hair and blue eyes to be counted twice.

3e = 33 . . . . add 3 and simplify

e = 11

11 students have blue eyes.

Answer:

The answer is "Option C".

Step-by-step explanation:

Given:

$\to f(x)=2x^2-3x+1\\\\when \ x=1\\\\\to f(1)= 2(1)^2-3(1)+1\\\\\to f(1)= 2(1)-3+1\\\\\to f(1)= 2-3+1\\\\\to f(1)=-1+1\\\\\to f(1)=0$

That's why choice C is correct.

If a rug is 6 feet wide by 8 feet long and suki makes a diagram that is 1 1/3 feet long how many inches should its width be

soldier1979 [14.2K]

The length in the diagram is 4/3 feet.
(4/3)/8=w/6 where w is the width.
So 4/(3×8)=w/6.
1/6=w/6 so w=1 foot or 12 inches.
