Answer:

50

Step-by-step explanation:

rectangle area = 144 cm

Formula: A= L*H

The give the length which is 16

144 = 16*H

Since they gave u the area instead of the height, work backwards

144/16 = 16/16 *H

9 = H

Now you have the length and height

Length: 16

Height: 9

Perimeter is when you add up all the sides

The top and bottom of the rectangle is the length which is 16 so

16 + 16 = 32

The left and right side of the rectangle is the height which is 9 so

9 + 9 = 18

Now add then both

32 + 18 = 50

So the perimeter of the rectangle is 50

Hope this helped!

When the polynomial is written in standard form, what are the values of the leading coefficient and the constant? 5x + 2 - 3x^2
earnstyle [38]
Leading coefficient = -3
Constant = 2

When you order them in standard form, you need to put them in ascending order of the exponents. Therefore the -3x^2 would come first, which makes the number attached (-3) the lead coefficient. 

Also, since the number (2) without an x attached would be last (due to the power of x technically being 0), than that is the constant.

Answer: X = kuv/ (u+v)

that means that x(u+v)/(uv) = k, a constant. so you want x such that,

x(3+3)/(3*3) = 3(3+1)/(3*1)

x=6

What happens to the graph of the line y = mx + b if the value of b is decreased?
ollegr [7]

Answer:

The lines moves lower.

Step-by-step explanation:

The steepness of a line is related to the slope, m.

b is the y-intercept, not the slope.

b is where the line intersects the y-axis.

Changing b changes the vertical position of the line.

Answer: The lines moves lower.

What is an equation of the line that passes through the point (-4,3) and is
zysi [14]

Answer:

The perpendicular line 4x − 5y = 20 has a slope of 4/5 and as such, the slope of the required line = -5/4

(y - 3)/(x + 4) = -5/4 simplify to get the required equation: 5x + 4y + 8 = 0
