Enter an expression equivalent to (3x^2+2y^2-3x)+(2x^2+y^2-2x)-(x^2+3y^2+x) using the fewest number of possible terms
Answer:
2x(2x - 3)
Step-by-step explanation:
Given:
(3x^2+2y^2-3x)+(2x^2+y^2-2x)-(x^2+3y^2+x)
Written as:
(3x² + 2y² - 3x) + (2x² + y² - 2x) - (x² + 3y² + x)
= 3x² + 2y² - 3x + 2x² + y² - 2x - x² - 3y² - x
Collect like terms
= 3x² + 2x² - x² + 2y² + y²- 3y² - 3x - 2x - x
= 4x² + 0 - 6x
= 4x² - 6x
= 2x(2x - 3)

Solve the equation x – 5 = 0.1(x + 5) for x
Answer:
Step-by-step explanation:
x - 5 = 0.1(x +5)
x - 5 = 0.1x + 5*0.1
x -5 = 0.1x + 0.5 {Add 5 to both sides}
x = 0.1x + 0.5 + 5
x = 0.1x + 5.5
x -0.1x = 5.5 {subtract 0.1x from both sides}
0.9x =5.5 {Divide both sides by 0.9}
x = 5.5/0.9
x = 55/9
x = 6 1/9
Answer:
x = ⁵⁵/₉ = 6¹/₉Step-by-step explanation:
x - 5 = 0.1(x + 5) {multiply both sides by 10}
10x - 50 = x + 5 {subtract x from both sides}
9x - 50 = 5 {add 50 to both sides}
9x = 55 {divide both sides by 9}
x = ⁵⁵/₉ = 6¹/₉

Estimate the square root of the following imperfect square:
7.
a. 2.2
b. 2.4
C. 2.6
d. 2.8
This problem is just try and error.
First we try number 2.5 since its the average of all the answers.
2.5^2=6.25
This is smaller than 7 so the answer is either 2.6 or 2.8
Now let's try 2.7
2.7^2=7.29
Which is bigger than 7 and that means the correct answer is 2.6 :)

Find the value of x. Round to the nearest degree as needed.
9514 1404 393
Answer:
x° = 29°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relevant trig relationships. Here, you have the hypotenuse and the side opposite the unknown angle. So, the appropriate relation is ...
Sin = Opposite/Hypotenuse
sin(x°) = 12/25
x° = arcsin(12/25) ≈ 28.69°
The value of x is about 29.
consider the expression
[tex]x4 - {y}^{2} [/tex]
when x = 3 and y = -6 , the value of the expression is *blank*
