Need HELP PLS PIC ATTACHED

Vera_Pavlovna [14]

Answer:

$4x^{2}$ -13x+10

Step-by-step explanation:

(4x+5)(x-2)

Multiply each term in the first parenthesis by each term in the second (foil)

Step 1: Expand it by writing out each multiplication. I added a picture showing which order to do it. (go in order of green, red, blue, yellow.) (you can remember this as first, outside, inside, last.)

When you expand it'll look like: 4x⋅x+4x⋅-2-5x-5⋅-2

Step 2: Calculate product

4x⋅x+4x⋅-2-5x-5⋅-2 (for the 4x⋅x it would be written like $4x^{2}$ )

$4x^{2}$ +4x⋅-2-5x-5⋅-2

$4x^{2}$ +4x⋅-2-5x-5⋅-2 (4x⋅-2 becomes -8x) (multiply 4x times -2)

$4x^{2}$ -8x-5x-5⋅-2

$4x^{2}$ -8x-5x-5⋅-2 (-5⋅-2 becomes +10) (multiply -5 times -2)

$4x^{2}$ -8x-5x+10

Step 3: collect like terms

$4x^{2}$ -8x-5x+10 (-8x-5x becomes -13x) (-8x times -5x)

$4x^{2}$ -13x+10 is the most simplified so it should be your final answer

Left to Right

Algebra I

Coordinates (x, y)

Algebra II

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

Step-by-step explanation:

*Note:

The distance formula is derived from the Pythagorean Theorem.

Step 1: Define

Identify

Point (5, 10)

Point (10, 12)

Step 2: Find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(10 - 5)^2 + (12 -10)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{5^2 + 2^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{25 + 4}$
[√Radical] Add: $\displaystyle d = \sqrt{29}$
