Rewrite the expression by factoring out the coefficient of the variable.​

Answer:

24 meters squared

Step-by-step explanation:

2 + 1 + 1 = 4

5 x 4 = 20

(2 x 1) x 2 = (2) x 2 = 4

20 + 4 = 24 meters squared

Answer:

-84

Step-by-step explanation:

20 + [-4(32 - 6) ]

Answer: Prime

A polynomial is  prime    if its only factors over the integers are 1 and itself.

==============================================================

Explanation:

Think of the idea of factoring whole numbers like factoring 36 into 6*6 which further breaks down into (2*3)*(2*3) = 2^2*3^2. This shows that 36 is composite and not prime.

Something like 7 is prime because the only factors are 1 and itself.

This idea extends into polynomials as well.

Something like x^2+4x+4 factors to (x+2)(x+2) which shows it is not prime. On the other hand, the polynomial x^2+3x+5 is prime over the integers because we cannot factor it like the previous example. The only factors here are 1 and itself.

Factoring is handy to help determine roots of a polynomial. However, other tricks could be used such as the quadratic formula or using numerical approximation techniques.

√5(√10 + √3) = √(5 · 10) + √(5 · 3) =

= √50 + √15 = √(25 · 2) + √15 =

= √(5² · 2) + √15 = 5√2 + √15 ← the end

Answer: C

Step-by-step explanation:

3x-3 ≥ 0 ==> x ≥ 1

3x+6 ≥ 0 ==> x ≥ -2

[tex] {(a + b)}^{2} - {(a - b) }^{2} \\ = 1[/tex]

In algebra 0 is written as 1 according to rule.

Answer:

a) 18

b)x^2+10x+18

c)x^2 -6x+2

Step-by-step explanation:

This is a case of plugging in the value into f(x).

a) f(-8)= -8^2 + 6(-8) +2

f(-8)= 64 + (-48) +2

f(-8)=64 + (-46)

f(-8)=18

b)  f(x+2)= (x+2)^2+6(x+2)+2

So here I'll take a break to explain what's going on, because x+2 is a binomial meaning two terms and it is being squared I have to multiply the whole thing by itself. Meaning: (x+2) x (x+2), this is also known as foiling!! and for the next part its distributing 6 into x and 2.

    f(x+2)= x^2+4x+4+6x+12+2

I'll reorder it

 f(x+2)= x^2+4x+6x+12+2+4

    f(x+2)= x^2+10x+18

c) f(-x)= -x^2+6(-x) +2

f(-x)= x^2 -6x+2

Answer:

x + x^2 = y*z

Step-by-step explanation:

equation: x+ x^2 = y*z

The sentence is converted into an equation or formula that will be x + x² = yz.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Translate the sentence into an equation or formula. The sum of x and its square is equal to y times z.

The square of the number x will be x². And the product of the numbers y and z will be yz. Then the equation will be

x + x² = yz

The sentence is converted into an equation or formula that will be x + x² = yz.

Answer:

[tex]x^2-6x+9[/tex]

Step-by-step explanation:

Say you have a function [tex]f(x)=x+1[/tex]. If you wanted to find f(3), you would replace the number in the parentheses, in this case 3, with x, to get [tex]f(3)=3+1=4.[/tex] When combining functions, you should do the same thing.

Here, we have [tex]f(x)=x^2.[/tex] We want to find f(g(x)). So, you should replace x in the function f(x) with the function g(x). [tex]g(x)=x-3.[/tex] So, f(g(x)) would equal [tex](x-3)^2[/tex], which equals [tex]x^2-6x+9[/tex].
