Answer:
f=20
Step-by-step explanation:
each rectangle = 8in
8+8=16
36-16= 20
Multiplying out the equation (x + 2)(4x - 3) and arranging in descending powers order gives us the quadratic form as; 4x² + 5x - 6
<h3>How to expand quadratic equations?</h3>
We want to expand the quadratic equation given as;
(x + 2)(4x - 3)
Multiplying out gives us;
4x² + 8x - 3x - 6
⇒ 4x² + 5x - 6
Thus, we can conclude that multiplying out the equation (x + 2)(4x - 3) and arranging in descending powers order gives us the quadratic form as; 4x² + 5x - 6

Answer:
A
Step-by-step explanation:
(800) × ( 3 × 10^-1)
= 8 × 10 ^2 × 3 × 10^-1
= 24 × 10^(2 - 1)
= 24 × 10^1
= 2.4 × 10^2
