You take the surface area of the square (6*6). And then add the SA of each triangle. (6*12)/2 (thats SA per triangle)
4(5y-8-2) = 185-15
20y-32-8 = 170
20y-40 = 170
+40 +40
20y = 210
Divide both sides by 20
Y= 10.5
The top rectangle = 7 x 12= 84 sq. inches
the bottom rectangle = 4 x 5= 20
the total area of the shape = 84 +20= 104 sq. inches
Answer:
5.0645km
Step-by-step explanation:
For the first part of the journey where Vail skied 2 km north, 2 km west
displacement = √2² + (-2)²
displacement = √4+4
displacement = √8
displacement = 2√2 km
d1 = 2√2 km
For the second part of the journey where he skeid 1 km north, and 2 km west. How far was she from her starting point?
displacement = √1² + (-2)²
displacement = √1+4
displacement = √5
d2 = √5 km
Total displacement = d1 + d2
Total displacement = 2√2 + √5
Total displacement = 2(1.4142) + 2.2361
Total displacement = 2.8284+ 2.2361
Total displacement = 5.0645km
Hence she was 5.0645km from her starting point
Im not 100% about how this question is explained or written but i think its 8
