Answer:
14x+6
Step-by-step explanation:
Multiply 7x by 2 which gets you 14x and multiply 3 by 2 which is 6.
Find the relationship between the two triangles. It’s 3.5 so you can use the Pythagorean theorem (sorry I forgot how to spell it)
A^2 + B^2= C^2
15^2 +8^2= C^2
225+64= C^2
289=C^2
C= 17
Then since they are similar triangles, multiply 17 by 3.5 and you get 59.5
That’s the answer!!
I can tell you that the opposite side of the triangle (the top) is also 11 those are two congruent sides
Find the amount of the increase:
8.13 - 6.19 = 1.94
Divide the amount of the increase by the original price:
1.94 / 6.19 = 0.3134
Multiply by 100:
0.3134 x 100 = 31.34%
Round to the nearest tenth = 31.3%
