The answer to this questions is letter B
A + b = 15 ..... eq 1
a – b = 12 ...... eq 2
So a = 15 – b
Substitute in eq 2 :
15 – b – b = 12
15 – 2b = 12
–2b = 12 – 15
b = 1.5
So a = 15 – 3/2 = 13.5
4ab = 4 x 13.5 x 1.5 = 81
Answer:
x=5
Step-by-step explanation:
since two sides are congruent, the two unknown angles are congruent.
All triangle angles total 180 degrees.
so:
180-88=92
92/2=46
9x+1=46
9x=45
x=5
Y-4=2/-3(x-6) I believe that’s the answer hope this helped
3/4a>-16
Multiply by the reciprocal of 3/4 on each side to get only a on one side of inequality.
a> -16 x (4/3)
That can be simplified to:
a > -64/3
a > -21 1/3
Hope this helps :)
