Answer:
tex]a^2 - 4b \neq 2[/tex]
Step-by-step explanation:
We are given that a and b are integers, then we need to show that 
Let 
If a is an even integer, then it can be written as 
, then,
RHS is a fraction but LHS can never be a fraction, thus it is impossible.
If a is an odd integer, then it can be written as 
, then,
RHS is a fraction but LHS can never be a fraction, thus it is impossible.
Thus, our assumption was wrong and .
Area of trapezoid = 1/2(b1+b2)(h)
<span>1/2(10 cm + 8 cm)(12cm) = </span>

Answer:
Step-by-step explanation:
11.
Area as sum: 
Area as Product: 7(d+4)
12. Area as sum: y*y+y*3
Area as Product: y(y+3)
Answer:
60g
Step-by-step explanation:
60/2=30
60+30=90
The additive inverse of a number is the opposite number......for this problem, it is a number, that when added to -4 1/4 = 0.
so the additive inverse of -4 1/4 = 4 1/4
