Answer:

X. The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!

(8x-7)+5 when x is 2<br><br>

Irina-Kira [14]

Answer:

If X=2 then the equation would be solved starting with 8x2=16 then take 16 and subtract it by 7 which would equal 9, then you take 9 and add 5 to it and that would give you the answer of 14

Step-by-step explanation:

(8x-7)+5 x=2

(8x2-7)+5

(16-7)+5

9+5

<u>Answer 14</u>

Which binomial is a factor of 8x^2y^3-18y

Musya8 [376]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the expression

$8x^2y^3-18y$

Apply exponent rule: $a^{b+c}=a^ba^c$

$8x^2y^3-18y=8yy^2-18y$ ∵ $x^2y^3=yy^2$

$=4\cdot \:2yy^2+9\cdot \:2y$

Factor out common term 2y

$=2y\left(4x^2y^2-9\right)$

We know that the Binomial is an expression that consists of two terms. Thus,

(4x²y²- 9) represents the binomial factor of $8x^2y^3-18y$

We can further simplify by Factoring 4x²y² - 9: (2xy + 3) (2xy - 3)

$=2y\left(2xy+3\right)\left(2xy-3\right)$

Here:

(2xy + 3) and (2xy -3) are the binomial factors of $8x^2y^3-18y$ as each of them consists of two terms.

Explain the difference between perimeter and area. What do they measure? What types of units are they measured in? NEED ANSWER S

kirill115 [55]

First the difference between the perimeter and area is that area is the amount of space inside a shape, and perimeter is the distance around the shape
^thats what they measure
And since perimeter is a length or distance, the unit of measure is inches, feet, yards, or miles. The area is usually found by doing l x w
