Solve for x. (x + 5)(x + 4) = 9x + 141
2 answers:
Answer:x=11 or x=-11
Step-by-step explanation: First, Use the FOIL method.
(x+5)(x+4)=9x+141
First:
Outer: 4x
Inner: 5x
Last: 5x4=20
Combine Like terms and write in standard form: +9x+20
Set up new equation:+9x+20=9x+141
Subtract 9x from both sides: +20=141
Subtact 20 from both sides: =121
Sqr root 121: =11
Remeber a sqr root of a positive number can be positive and negative so x= 11 or -11

a. FALSE. Because f(4.9) will round down to 4.
b. TRUE.
c. no it's not the absolute value function. that has V-shape
d. TRUE.
