Answer:
Step-by-step explanation:
The irregular shape's area consists of the sum of the areas of all the shapes that make it up.
Area of pink triangle: 
Area of purple square: 
Area of green quadrilateral: 
Area of blue triangle: 
Therefore, the area of the irregular polygon is 
.
The perimeter of the irregular polygon consists of certain shred sides from the four polygons that make up:
Answer:
1,if Noah is 15 his cousin is 8 or 96 months
2, and when Noah's cousin is 132 months or 11 years old Noah will be 18
3,n-[[7]12]=age of Noah's cousin
Step-by-step explanation:
1,15-7=8
1 part 2, 8*12=96
2,132/12=11
2 part 2,
11+7=18
3,n-[[7]12]=age of Noah's cousin
4,n+[7/12]
if n=18
18+[7/12]
or
18+0.5833=18.5833
Answer:
<h2>-4</h2>
Step-by-step explanation:
Given the line containing the points.
x | -7. -6. -5. -4
y | 21. 17. 13. 9
The slope of the line is expressed as m = Δy/Δx = y₂-y₁/x₂-x₁
Using the coordinates y (21, 17) and corresponding value of x(-7, -6)
y₁ = 21, y₂ = 17 x₁ = -7, x₂ = -6
Substituting the values into the formula for calculating the slope, we have;
m = Δy/Δx = 17-21/-6-(-7)
m = -4/-6+7
m = -4/1
m = -4
<em>Hence the slope of the line that contains these points is -4</em>
Answer:
n= 12
Step-by-step explanation:
12 times 2 gives you 36
12 times 4 gives you 48.
12 is both factors of these numbers
