Answer:
x^2 - 7x - 1
Step-by-step explanation:
g(x) = x^2– 5x
f(x) = 2x +1
(g - f)(x)
expand to get
gx - fx
Slot in the values
(x^2– 5x) - (2x +1)
expand
x^2 - 5x - 2x - 1
x^2 - 7x - 1
Answer:
the answer is b . 0.4405 which is 0.44
Step-by-step explanation:
just divide and subtract
Answer:
let w = the width of the rectangle
let w- 9=the length of the rectangle
A= L×W
220=w(w-9)
220=w^-9w
w^-9w-220=0
(w-20)(w+11)=0
w-20=0 or w+11=0
w=20cm or x-11 illogical answer
The integers are 12,14 and 16
<h3>How to determine the integers?</h3>
Consecutive even integers are represented as:
x, x + 2 and x + 4
So, the statement is represented as:
7 * (x + x + 2 + x +4) = 140 + 11 * (x + 2)
Evaluate the like terms
7 * (3x + 6) = 140 + 11 * (x + 2)
Open the brackets
21x + 42 = 140 + 11x + 22
Collect the like terms
21x -11x =
Evaluate
10x = 120
Divide by 10
x = 12
So, we have
x + 2 = 14
x + 4 = 16
Hence, the integers are 12,14 and 16
