Answer:

Option (B). Perimeter of the quadrilateral ABCD= 14.6 units

Step-by-step explanation:

From the figure attached,

Coordinates of the vertices are A(3, 5), B(1, 3), C(3, -1), D(5, 3).

Length of AB = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}$

= $\sqrt{(3-1)^2+(5-3)^2}$

= $\sqrt{8}$

= 2.83 units

Length of AD = $\sqrt{(3-5)^2+(5-3)^2}$

= $\sqrt{8}$

= 2.83 units

Length of BC = $\sqrt{(1-3)^2+(3+1)^2}$

= $\sqrt{20}$

= 4.47 units

Length of DC = $\sqrt{(5-3)^2+(3+1)^2}$

= $\sqrt{20}$

= 4.47 units

Perimeter of the quadrilateral = AB + AD + DC + BC

= 2.83 + 2.83 + 4.47 + 4.47

= 14.6 units

Option (B) is the answer.

poizon [28]

He'd have to sell 268 items

268x $1.50 = 402

$402 + $54 = $456

Evaluate. 102+6⋅7+8 70142150190

Aloiza [94]

Hi.

102+6(7)+8 (your equation)
102+ 42+ 8 (since the order is PEMDAS, multiplication has to go first. 6x7=42
144 + 8 (since you go left to right, 102 +42 has to be 1st. Answer= 144)
152 (now the only thing left is 144 + 8, so do that. Answer= 152.)

Since that's the last step, 152 will be your answer.

Hoped I helped and if you need anymore you could always ask me~
