Answer:

4 cm and 7 cm

Step-by-step explanation:

Given that Juanita is cutting a piece of construction paper in the shape of a parallelogram. Two opposite sides of the parallelogram have lengths (5n − 6) cm and (3n − 2) cm.

We know that opposite sides are equal in a parallelogram.

Hence we have

5n-6 = 3n-2\\2n =4\\n=2

Hence the side length = 5(2)-6 =4 cm

The adjacent side = 2n+3\\=2(2)+3\\=7cm

Thus answer is 4 cm and 7 cm

Use slope to determine if the following lines are parallel, perpendicular, or neither.
Gwar [14]

Answer:

The lines are parallel, with the same slope of 5.

Step-by-step explanation:

Remember that if slopes are the same, then the lines are parallel. If the slopes are opposite reciprocals, they are perpendicular. If they are neither of those cases, then they would be neither.

1) Since y = 5x + 1 is already in slope-intercept format (y = mx + b, in which m represents the slope) we know that 5 is the slope of that equation.

2) To find the slope of -5x + y = 6, let's just convert it to the slope-intercept format by isolating y on the left side like so:

-5x + y = 6 \\y = 5x + 6

(All you need to do is move -5x to the right side of the equation.) So, by looking at y = 5x + 6, we can do the same thing we did from step 1 and find that the slope is 5.

3) Since both of the equations' slopes are 5, they share the same slope - therefore, they are parallel.

Hope this helps! Please do not hesitate to ask any questions.

No. 1 is inductive, cos the evidence is based on proberbility as not all pennies are silver color, since thier color could change over time (fade)

while

No 2 is deductive since all even numners are divisible by 2, there is a full assurance of the outcome.

Naddik [55]
Class 1= 6+x
class 2 = x
total= 50
so you need to find the x
50=6+x+x
50=2x+6
50-6=2x
44=2x
22=x
22+6
28 is the larger class
