Brighten is an expression that shows how to multiply 7 * 256 using expanded form and distributive property

charle [14.2K]

I am not familiar with "brighten" but this is how you can expand and use the distributive property:

7(256)

= 7(200 + 50 + 6)

= 7(200) + 7(50) + 7(6)

= 1400 + 350 + 30

= 1780

Explain these questions, please

How I was taught: Make sure both numbers are a fraction. If not put "1" as the denominator. Multiply straight across. Simplify if you can.

Answer:

$\displaystyle d = 34$

General Formulas and Concepts:

Addition
Subtraction

Left to Right

Algebra I

Coordinates

Algebra II

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (-1, -13)

Point (-1, 21)

Step 2: Find distance d

Substitute in points [DF]: $\displaystyle d = \sqrt{(-1+1)^2+(21+13)^2}$
(Parenthesis) Add: $\displaystyle d = \sqrt{(0)^2+(34)^2}$
[√Radical] Simplify: $\displaystyle d = \sqrt{(34)^2}$
[√Radical] Evaluate: $\displaystyle d = 34$
