Answer:

True

Step-by-step explanation:

If A/B and C/D are rational expression then

A/B*C/D

A/B*C/D=A/C*B/D

It means that if A/B and C/D are rational expression then their product with each other will also be a rational expression.

If f(x)=3x+1 and g(x)=x^2-6 find (f-g)(x)

8090 [49]

Hi there!

• f(x) = 3x + 1
• g(x) = x² - 6

Then,
According to th' question :-

(f - g)(x) = f(x) - g(x)

= 3x + 1 - (x² - 6)

= 3x + 1 - x² + 6

= -x² + 3x + 7

Hence,
Option 2ⁿᵈ : -x² + 3x + 7 is Correct.

~ Hope it helps!

Let R be the greater radius and r be the smaller radius

A) Area of the sidewalk = R^2 - r^2 - This can be the expression

B) = 3.14
=(R^2-r^2)
=(11^2-9^2)
=(121-81)
=*40

That was the simplified expression

Answer = 3.14 * 40 = 125.6m^2
