3x^2 - x - 2

Step-by-step explanation:

<u>Step 1:  Combine like terms</u>

(2x^2- 4x + 5) + (x^2 + 3x - 7)

2x^2 - 4x + 5 + x^2 + 3x - 7

(2x^2 + x^2) + (-4x + 3x) + (5 - 7)

3x^2 - x - 2

The sum of two numbers is 12. The difference of the same two numbers is 24. what is the larger of the two numbers
Vsevolod [243]

ANSWER


The larger number is 18

<u>EXPLANATION</u>

Let x be the larger number and y be the smaller  number.


Then,

x+y=12--(1)


x-y=24--(2)


Let us add equation (1) and (2).


2x=36


Divide through by 2


x=18


Put x=18 in to equation (1).

This implies that,

18=y=12



y=12-18=-6

The area of rhombus ABCD is 72 square units. EC = 8 units and DB = x – 1. What is the value of x?
Black_prince [1.1K]
IF EC = 8, than we know for sure that the length of AC would be 2 x 8 = 16

The formula to use in determining Rhombus area is 
A = (AC . DB)/2 , so the value x could be found with this equation :

72 = 16 (x-1)     /  2

72 = (16x -16) /2

72 = 8x - 8

80 = 8x 

x = 10
