Answer:
The most simplified form is 15√10
Step-by-step explanation:
1. Let's simplify the expression:
20√270 ÷ 4√3
20√9 * 30/ 4√3 (√270 = √9 * 30)
60 √30/ 4√3
(60 √3 * √10) / 4√3 (√30 = √3 * √10)
60/4 √10 ( We cancel √3 in the numerator and in the denominator)
15√10
The most simplified form is 15√10
Answer:
-21x + 6x - 4
Step-by-step explanation:
First, distributive property.
-7(3x) = -21x
2(3x-2) = 6x - 4
Secondly, put those together.
-21x + 6x - 4
And that is your answer because you don't need to find the sum or x.
Answer:
2 3/10, 2.59, 24
Step-by-step explanation:
(y-2) (x + 3) are factors of the xy + 3y-2x-6 form
Factoring is a statement of a form of addition into a multiplication
There are several factoring of the following forms:
factoring:
ax + ay + az = a (x + y + z + ...)
ax + bx -cx = x (a + b-c)
factoring:
x²-y² = (x-y) (x + y)
factoring:
x² + 2xy + y² = (x + y) (x + y) = (x + y)²
x²-2xy + y² = (x-y) (x-y) = (x-y)²
factoring:
ax² + bx + c = (x + m) (x + n) with m x n = c and m + n = b
factoring:
can be completed in 2 ways
a. distributive way
ax² + bx + c = ax² + px + qx + c with
p x q = a x c and
p + q = b
b. formula way
ax² + bx + c = 1/a (ax + m) (ax + n) with
m x n = a x c and
m + n = b
So from an addition form, for example:
ax + ay = a (x + y), then a and (x + y) are factors of the form ax + ay
So (y-2) (x + 3) are factors of the form xy + 3y-2x-6

Answer:
Domain = all real numbers
Step-by-step explanation:
The domain of a function is the set of x-values for which the function is defined.
When we have a graphical representation of a function, we look if the function is continuous for all values of x or not. If it is, the domain is the set of all real numbers. If it is not, we look from what value till what value the function is defined for , x-values basically.
Looking at this function, we see that it stretches forever to the left and forever to the upward direction (also advancing right limitless as well).
We want the domain (x values), which concerns with LEFT and RIGHT. So, we can see that this function is continuous for all values of x (it goes on and on to right and left). So we can say the domain is the set of all real numbers.
Domain = all real numbers
