Answer: 5 and 4

Step-by-step explanation:

Perimeter = 2 ( L + W)

18 = 2(L + W) divide through by 2

9 = L + W

9 - L = W

Area = L * W

20 = L (9 - L)

20 = 9L - L^2

L^2 - 9L + 20 = 0 factor

(L - 5) (L - 4) = 0

Set both factors to 0 and solve for L

L = 5 and L = 4

What is the equation of the line on the graph? Write your answer in slope-intercept form. (y = mx + b)
Nikolay [14]

Answer:

y= ⅔x -2

Step-by-step explanation:

<u>slope-intercept </u><u>form</u>

y= mx +b, where m is the slope and b is the y-intercept.

Two given coordinates: (-3, -4) and (6, 2)

\boxed{slope =  \frac{y1 - y2}{x1 - x2} }

Slope

=  \frac{2 - ( - 4)}{6 - ( - 3)}

=  \frac{2 + 4}{6 + 3}

=  \frac{6}{9}

=  \frac{2}{3}

Substitute m= ⅔ into the equation:

y= ⅔x +b

From the graph, the y- intercept is -2 since the line cuts through the x-axis at (0, -2).

Alternatively, we can also substitute a pair of coordinates into the equation to find the value of b.

When x= 6, y= 2,

2 =  \frac{2}{3} (6) + b

2= 4 +b

b= 2 -4

b= -2

Thus the equation of the line is y= ⅔x -2.

Please help. The topic is angles. Anything you know helps
Lorico [155]

Answer:

all of them except straight and reflex

Step-by-step explanation:

when angles are supplementary it means that they add up to 180

an acute angle is supplementary to an obtuse angle

an obtuse angle is supplementary to an acute angle

a right angle is supplementary to a right angle

but a reflex angle is over 180 so it's not supplementary to anything

and a straight angle is already 180 so it has no supplements either
