(2x-4)(x+5) expand with indicated multiplication
2x^2+10x-4x-20
2x^2+6x-20
Answer:
$1.50 dollars per bag and at that rate it would be $7.50 for 6 bags of chips
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
22+54x=20+60x
54x=-42+60x
-6x=-42
x=7
Answer:
x = 7 degrees
Step-by-step explanation:
4x-5 = 2x + 9
-2x -2x
2x-5 = 9
+5 +5
2x = 14
2x/2 =14 /2
x= 7
F(x) = sin(x) + icos(x)
|f(x)| = sqrt(sin^2(x) + cos^2(x)) = sqrt(1) = 1
Therefore, |f(x)| = 1
