16.  would be C since they both consist of the same variable to the same power

17. x-2x+7-9+4x
     c. 3x-2
18. -4(3a-5). You would multiply -4 by 3 a, and -4 by -5. It turns to
      -4(3a)-4(-5)
     a. -12a+20

The length of a rectangle is 3 yd more than twice the width, and the area of the rectangle is 54 yd?. Find the dimensions of the
s344n2d4d5 [400]

Answer:

The length of the rectangle is 37 yards, and the width of the rectangle is 17 yards.

Step-by-step explanation:

Given that the length of a rectangle is 3 yards more than twice the width, and the area of the rectangle is 54 yards, the following calculation must be performed to find the dimensions of the rectangle, knowing that the area of a rectangle arises from multiplying its base by its height:

2X + 3 + X = 54

3X + 3 = 54

3X = 54 - 3

X = 51/3

X = 17

(17 x 2) + 3 = 37

Therefore, the length of the rectangle is 37 yards, and the width of the rectangle is 17 yards.

Consider the relation y = −8|x + 3| − 9. what are the coordinates of the vertex? (−3, 9) (−3, −9) (3, −9) (3, 9)
german
By simple substitution on the left side and on the right side of the given equation, we have to
 For <span>coordinates (-3,-9)
 -9</span><span>=−8|-3+3|−9
 -9</span><span>=−8|0|−9
</span> -9=−9
 Therefore, it is demonstrated that<span> the coordinates of the vertex is
 (-3,-9)</span>

What is the equation of a line passing through point (6, -2) and has a y-intercept of 8?
Whitepunk [10]

Answer:

y = -1.667(x) + 8

Step-by-step explanation:

Slope intercept form = (y = mx+b)

X = 6

Y = -2

Y-int = 8

Substitute the values

-2 = m(6) + 8

-10 = m(6)

-1.667 = m
