Answer:

The correct answer is third option,

32 square units

Step-by-step explanation:

Points to remember

1). Distance formula

The distance between two points (x1, y1) and (x2, y2) is given by,

Distance = √[(x2 - x1)² +(y2 -y1)²]

2. Area of parallelogram = bh

Where b - Length of parallelogram

h - Height of parallelogram

To find the distance of UT and RU

By using distance formula

UT = √[(x2 - x1)² +(y2 -y1)²]

= √[(6 - 0)² +(2 - 0)²] = 5.6

RU = √[(x2 - x1)² +(y2 -y1)²]

= √[(-4 - 0)² +(4 - 0)²] = 5.6

To find the area of parallelogram 

Area = bh

= 5.6 * 5.6

≈ 32 square units

A grocery store sells a bag of 6 oranges for $2.34. If Mav spent $1.95 on oranges, how many did she buy?

poizon [28]

Answer:

5 oranges

Step-by-step explanation:

to solve this problem we need to make a cross-multiplication equation

2.34 is to 6 as 1.95 is to ?

? is the number of oranges that are needed to be found that were bought

2.34/6 = 1.95/?

Now we cross multiply 6 and 1.95 = 11.7

11.7/2.34 = 5

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 (-5, 6) → x₁ = -5, y₁ = 6

Point (3, 2) → x₂ = 3, y₂ = 2

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formulas]: $\displaystyle d = \sqrt{(3+5)^2+(2-6)^2}$
[Distance] [√Radical] (Parenthesis) Add/Subtract: $\displaystyle d = \sqrt{(8)^2+(-4)^2}$
[Distance] [√Radical] Evaluate exponents: $\displaystyle d = \sqrt{64+16}$
[Distance] [√Radical] Add: $\displaystyle d = \sqrt{80}$
[Distance] [√Radical] Simplify: $\displaystyle d = 4\sqrt{5}$
