Answer:

3) x = 9

4) x = 3

Step-by-step explanation:

3) The two short segments are indicated as having a sum equal to the long segment.

(x +2) +(-5 +x) = 15

2x = 18 . . . . . . . . . . . . add 3

x = 9 . . . . . . . . . divide by 2

(This makes the segments be 9+2 = 11 and -5+9 = 4, which total 15.)

4) Same deal.

3x +3 = 4x

3 = x . . . . . . . . subtract 3x

(This makes the segments be 3(3) = 9 and 4(3) = 12, where 9+3=12.)

What are the factors of the square root of 329

Andru [333]

Answer: $x=-\dfrac{3}{2}, 7$

Step-by-step explanation:

$2x^2-10x-26=x-5$

$2x^2-10x-26-x+5=0$ Move all terms to one side

$2x^2-11x-21=0$ Simplify $2{x}^{2}-10x-26-x+5$

$2x^2+3x-14x-21=0$ Split the second term

$x(2x+3)-7(2x+3)=0$ Factor out common terms in the first two terms, then in the last two terms.

$(2x+3)(x-7)=0$ Factor out the common term $2x+3$

$x=-\dfrac{3}{2}, 7$

On the first day of winter, the temperature in Cassville was – 3°F. That same day, the temperature in Shorewood was – 11°F

just olya [345]

Answer:

Step-by-step explanation:

___________________________________________________________

-11 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0

Okay so on this number line that I made you see -3 degrees F and -11 degrees F. All you have to do is count, start at -3 and count the numbers until you get -11 so the answer would be -8 degrees F because it takes 8 units to get to 7 on the negative number line.
