A=bh
A/h bh/h
A/h=b
The answer s b= a/h
Answer:
a = 3
Step-by-step explanation:
Factorize (x+5)(x-4)(x+2)
(x+5)(x-4)(x+2)
= (x²-4x+5x-20)(x+2)
= (x²+x-20)(x+2)
= (x³+2x²+x²+2x-20x-40)
= x³+3x²-18x -40
Compare with x^3+ax^2
3x² = ax²
3 = a
Rearrange
a = 3
Hence the value of a that makes the expressions identical is 3
Answer:
539
Step-by-step explanation:
Solve for d in d + e = 2
d = 2 - e
Substitute d = 2 - e into d - 3 = 4
2 - 2e = 4
Since 2 - 2e = 4 is false, this is an inconsistent system
<em>No solution exists. </em>
