Monica made 1 red bracelet and 4 blue bracelets. she made twice as many black bracelets as red bracelets. she told her friend she made 7 bracelets.

was monica's calculation reasonable?

a.
yes, it is reasonable because 1 + 4 + 2 = 7.

b.
no, it is not reasonable because 1 + 4 + 5 = 10.

c.
no, it is not reasonable because 1 + 4 + 8 = 13.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
