Answer:

Step-by-step explanation:
Pay attention to the two tick marks. This indicates that those sides are congruent to each other and so will the angles on the bottom and top. Therefore, we can set up the equation
and solve for x:






So basically you just need to do the Pythagorean theorem to find the sides of the shaded rectangle, with c being the length of the side.
Small side:
2^2 + 6^2 = c^2
4 + 36 = c^2
40 = c^2
C is similar to 6.32456
Long side:
12^2 + 4^2 = c^2
144 + 16 = c^2
160=c^2
C is similar to 12.64911
And then you just multiply!
Answer:
47.5 miles
Step-by-step explanation:
So, every morning, you travel 4.75 miles to get to school... and another 4.75 miles in the afternoon to return.
So, each day, you travel a total of 9.5 miles (4.75 + 4.75) to go school and back.
On a typical school week, you'll go to school 5 times... so you'll need to travel a total of 47.5 miles (5 * 9.5).
Answer: C
Step-by-step explanation: since the x’s are common terms, you just add them together
