Answer:

Actual                                      2/3

30 inch. by 12 inch               240 inch²

30 inch. by 18 inch               360 inch²

12 inch. by 15 inch                  120inch²

18 inch. by 15 inch                 180inch²

Step-by-step explanation:

The answers are given in the same line .

Actual                                                      1/3                          2/3

30 inch. by 12 inch                                120 inch²                 240 inch²

30 inch. by 18 inch                                180 inch²                 360 inch²

12 inch. by 15 inch                                  60 inch²                  120inch²

18 inch. by 15 inch                                90 inch²                    180inch²

We  find the areas and multiply by 2/3 to get the answers

30 * 12= 360 inch²

2/3 * 360 = 240 inch²

30 * 18= 540 inch²

2/3 * 540 = 360inch²

12 * 15= 180 inch²

2/3 * 180 = 120 inch²

18 * 15= 270 inch²

2/3 * 270 = 180inch²

UNO [17]

Answer:

<em>2 solutions</em>

Step-by-step explanation:

Given the expression

2m/2m+3 - 2m/2m-3 = 1

Find the LCM of the expression at the left hand side:

2m(2m-3)-2m(2m+3)/(2m+3)(2m-3) = 1

open the bracket

4m²-6m-4m²-6m/(4m²-9) = 1

Cross multiply

4m²-6m-4m²-6m = 4m²  - 9

-12m = 4m²  - 9

4m²  - 9+12m = 0

4m² +12m-9 = 0

<em>Since the resulting equation is a quadratic equation, it will have 2 solutions since the degree of the equation is 2</em>

What is the lmc of two numbers that have no common factors greater then 1
Luba_88 [7]
We can take prime numbers so they don't have a common factor other than 1.

3, and 5.

So we have to list the multiples to find the LCM

3: 3, 6, 9, 12, 15, 18
5: 5, 10, 15, 20, 25

15 is the LCM of 3 and 5

So, you can notice that if two numbers, lets call them a and b, have no common factor, then a \times b is the LCM.

Hope that helped :)
