Solve #1 pls, I need to find the shortest side, median side, and longest side

Answers

Answer:

Shortest side = 39 cm.

Median side = 65 cm.

Longest side = 91 cm.

Step-by-step explanation:

The perimeter in total is 195 cm. The ratio of the sides are 3 : 5 : 7.

First, find how much parts there are as a whole, by combining the ratios:

3 + 5 + 7 = 15 parts.

Divide the total of parts from the total measurement:

195/15 = 13

Each part has the measurement of 13 cm.

1 part = 13 cm.

Use the following ratio to solve for each of the sides:

Shortest side: 3

3 x 13 = 39

Shortest side = 39 cm.

Median side: 5

5 x 13 = 65

Median side = 65 cm.

Longest side: 7

7 x 13 = 91

Longest side = 91 cm.

Check. Combine all side measurements together. They should equal 195:

39 + 65 + 91 = 195

(39 + 65) + 91 = 195

(104) + 91 = 195

195 = 195 (True).

The length, 18 meters, is the answer to the following question."The length of a rectangle is three meters longer than its width. The area of the rectangle is 270 square meters. What is the length of the rectangle?"
Rework this problem: Write an equation using ???? as the length (in meters) of the rectangle that would lead to the solution of the problem. Check that the answer above is correct by substituting 18 for ???? in your equation.

Answers

Answer:

L = B + 3 ..................(1)

L × B = 270 m² .................(2)

on solving we get

L = 18 m, B = 15 m

Step-by-step explanation:

Let the length of the rectangle be L

and,

Width of the rectangle be 'B'

thus,

according to the question

L = B + 3 ..................(1)

And, area of the rectangle = 270 m²

also,

Area of the rectangle = L × B = 270 m² ...........(2)

on substituting 'L' from equation 1 in equation 2, we get

( B + 3 ) × B = 270

B² + 3B - 270 = 0

B² + 18B - 15B - 270 = 0

B( B + 18 ) - 15(B + 18) = 0

( B - 15 ) × ( B + 18 ) = 0

thus, we get

B = 15 m (accepted ) and B = -18 m (neglected : since the length cannot be negative)

therefore,

From 1, we get

L = 15 + 3 = 18 m

Answers

for two line segments to be parallel, their slopes must be equal.

Therefore slope of AB must be equal to slope of CD

which is, option 3
(y4-y3)/(x4-x3)=(y2-y1)/(x2-x1)

the complete question in the attached figure

we know that

Two lines are parallel if they have the same slope.

Computing for the slope of line segment AB and line segment CD using the formula

$m=((y2-y1))/((x2-x1))$
