Answer:

$p=28.2\:\text{units},\\A=40.2\:\text{square units}}$

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: $\frac{1}{2}\cdot 3 \cdot 3=4.5$

Area of purple square: $3^2=9$

Area of green quadrilateral: $3\cdot 2.9=8.7$

Area of blue triangle: $\sqrt{10.25(10.25-8.5)(10.25-6)(10.25-6)}=17.99989$

Therefore, the area of the irregular polygon is $4.5+9+8.7+17.99989\approx \boxed{40.2\:\text{square units}}$ .

The perimeter of the irregular polygon consists of certain shred sides from the four polygons that make up:

$p=3+3+3+4.2+3+6+6=\boxed{28.2\:\text{units}}$

Answer:

d = 5

Step-by-step explanation:

We want to know what d would be when x = -1, so we can start off by plugging in -1 for x to get the following equation: $\sqrt{8 - (-1)} = 2(-1)+d$ . On the left hand side, 2 negatives become a positive sign, so the -(-1) becomes a +1, and 8+1 would equal 9. On the right hand side, we just multiply 2 and -1 to get -2. So, the equation now looks like this: $\sqrt{9} = d-2$ . We know that $\sqrt{9}$ = 3, so we would get 3 = d-2. THen we would add 2 to both sides to get d = 5. Hope this helps!
