Let's do this: start with f(x) = x -1. Now substitute the label "g(x)" for x:
f(g(x)) = g(x) - 1 and we are told that f(g(x)) equals x + 1.
Thus, g(x) - 1 = x + 1
Adding 1 to both sides, we get
g(x) = x + 2 (answer)
<h3>Part A</h3>
<u>Factoring the area:</u>
- 4x² + 20x + 25 =
- (2x)² + 2*2x*5 + 5² =
- (2x + 5)²
<u>The length of the side is:</u>
<h3>Part 2</h3>
<u>Factoring the area:</u>
- 4x² − 9y²=
- (2x)² - (3y)² =
- (2x + 3y)(2x - 3y)
<u>The sides of the rectangle are:</u>
Answer:
PB = 1.8
Step-by-step explanation:
PQ = 8 cm, BC = 10 cm and AB = 9 cm
∆ABC is similar to ∆APQ.
Therefore:
Plug in the values
Cross multiply
AP × 10 = 8 × 9
AP × 10 = 72
Divide both sides by 10
AP = 7.2
PB = AB - AP
PB = 9 - 7.2
PB = 1.8
that's correct, what you've put in the boxes. :)
