Use the distributive property to simplify 5(w + 6) =
Answer:
5w+30
5(w+6)=
5*w= 5w
5*6= 30
Answer:
[tex]\huge\boxed{\boxed{5w+30}}[/tex]
Step-by-step explanation:
Hello.
The Distributive property states that
a(b+c)=ab+ac
Let's use this property to simplify:
5(w+6)
5w+30 (5 times w and 5 times 6)
And we're done!
I hope it helps & have an outstanding day!

solve for z: -21 = z - (-6 - 2z)
Answer:
z = -9
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Algebra I
Terms/Coefficients/DegreesStep-by-step explanation:
Step 1: Define
-21 = z - (-6 - 2z)
Step 2: Solve for z
Distribute negative: -21 = z + 6 + 2zCombine like terms: -21 = 3z + 6Isolate z term: -27 = 3zIsolate z: -9 = zRewrite: z = -9Answer:
Step-by-step explanation
-21-6=2z+z

The function y = f (x) is graphed below. What is the average rate of change of the function f(x) on the interval - 1 ≤ x ≤ 3?
Answer:
[tex]\displaystyle -2[/tex]
General Formulas and Concepts:

Answer:
this is 8 raise to power 18
Answer:
8^18.
Step-by-step explanation:
The Law of exponents.
(x^a)^b) = x^(ab)
Why this happens?
(8^6)^3
Imagine you have 8^6.
8*8*8*8*8*8 to the power of three or ^3.
(8*8*8*8*8*8)^3.
8*8*8*8*8*8*8*8*8*8*8*8*8*8*8*8*8*8*8*8 which = 8^18.
This is why (8^6)^3=(8^(6*3) or 8^18.
Hope this helps plz hit the crown :D

Which ordered pair is not a point on the graph of y = 1/2 x - 7?
A. (1, -6 1/2) B. (-2, -8) C. (0, -7) D. (2, 8)
What is the distance between (2, -2) and (-8, -2)?
Given:
(2, -2)(-8, -2)To find: The distance between the two points.
Answer:
Formula to find the distance:
[tex]\sf Distance\ =\ \sqrt{\Bigg(x_2\ -\ x_1\Bigg)^2\ +\ \Bigg(y_2\ -\ y_1\Bigg)^2}[/tex]
From the given data, we have:
x₁ = 2x₂ = -2y₁ = -8y₂ = -2Using them in the formula,
[tex]\sf Distance\ =\ \sqrt{\Bigg(-8\ -\ 2\Bigg)^2\ +\ \Bigg(-2\ -\ (-2)\Bigg)^2}\\\\\\\\Distance\ =\ \sqrt{\Bigg(-10\Bigg)^2\ +\ \Bigg(-2\ +\ 2\Bigg)^2}\\\\\\\\Distance\ =\ \sqrt{100}\ =\ \bf 10\ units.[/tex]
Therefore, the distance between (2, -2) and (-8, -2) is 10 units.
Hope it helps. :)
