if you're asking for the written out problem in an equation for it's 6 divided by 12
Answer:
A = 39 ft
B = 2A = 78 ft
C = A + 21 = 60 ft
Step-by-step explanation:
let A be the short side,
B = 2A
C = A + 21
A + B + C = 177
A + 2A + A + 21 = 177
4A = 156
A = 39
Answer:
Please see the attached picture for the full solution.
*From the 4th line of the 1st image, you could also expand it using
(a +b)²= a² +2ab +b² and
(a -b)²= a² -2ab +b².
When squaring a fraction, square both the denominator and numerator.
➣(a/b)²= a²/b²
OH MY GOSH I THINK I GET IT! difference as in division. it wants you to i think make for example make 2 the answer to an equation like 5-3=2! 5 and 3 are prime numbers.
