Answer:
<h2><u><em>
Area = x² + 8x + 12</em></u></h2><h2><u><em>
Perimeter = 4x + 16</em></u></h2>
Step-by-step explanation:
The area of a rectangle is given by the formula:
Area=width×height
The perimeter of a rectangle is given by the formula
Perimeter=2(width+height)
Area
(x + 6) × (x+2) =
x² + 2x + 6x + 12
x² + 8x + 12
------------------
Perimeter
2 × (x + 6 + x + 2) =
2 × (2x + 8) =
4x + 16
Answer:
2/5
Step-by-step explanation:
To find the slope of a line segment, find the difference in y and divide by the difference in x (delta y / delta x)
Delta y: -7 - (-13) = 6
Delta x: 15 - 0 = 15
Slope = delta y / delta x
Slope = 6/15 = 2/5

Answer:
3x + 6 =27
Step-by-step explanation:
A. The solution is 7! First I Subtracted 6 from both sides of the equation, Then I Divided both sides of the equation by the same term. Then I got "7" from doing the following.
B. The solution is the x in the answer which is the amount of juice he poured.

Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
( substitute in values )
= 
( cross- multiply )
12(x - 1) = 72 ( divide both sides by 12 )
x - 1 = 6 ( add 1 to both sides )
x = 7

The parallel line segment SV is half of RW
that is x = 7.5
SV also divides the sides RT and WT in proportion, that is
= 
( cross- multiply )
10y = 24 ( divide both sides by 10 )
y = 2.4
