Divide all the ratios and compare:
8/12 = 0.666
15/10 = 1.5
2/3 = 0.666
6/9 = 0.666
The one that isn't equivalent is 15 over 10
Larger triangle’s base length
a^2 + b^2 = c^2
a^2 + 3^2 = 8^2
a^2 = 8^2 - (3^2)
sqrt(a^2) = sqrt(55)
a = sqrt(55)
__________________
Smaller triangle’s base length:
The same formula applies.
a^2 + 3^2 = 5^2
a^2 = 5^2 - (3^2)
sqrt(a^2) = sqrt(16)
a = 4
____________
The finale!
Add the two side lengths of a, which is sqrt(55) + 4 (exact answer)
or... 11.416 (unrounded to thousandths place)
Good luck to you!
Answer:
C
Step-by-step explanation:
Hello there!
2x - 7 = 3
Solve for x
2x = 3 + 7
2x = 10
x = 10/2
x = 5
Therefore, the number of x in the equation is 5
