Start by finding a common denominator.
In this case, it would be 21.
So, -12/21 + -28/21= -40/21
Answer:
68,643
Step-by-step explanation:
work backwards
261×263=68,643
68,643÷263=261
It is 36 feet
A=1/2bh
a=1/2*12*6
a=6*6
a=36feet squared
hope this helps!
Isosceles triangle, angle P = angle Q.
3x + 10 = x + 52
2x = 42
x = 21
Congruent angles are both x+52=73 degrees. Triangle angles add to 180 so
y = 180 - 73 - 73 = 34 degrees
Answer: 34
