Answer:

(f+g)(x) = √(4x+6) + √(4x-6)

Step-by-step explanation:

f(x) = √(4x+6)

g(x) = √(4x-6)

(f+g)(x) = f(x) + g(x)

(f+g)(x) = √(4x+6) + √(4x-6)

WHAT IS THE LENGTH OF AC? Help me!!!

nasty-shy [4]

Given triangles are similar, so we setup a proportion

(140-x)/81 = x/9

solving gives x = 14
AC = 140-x = 140-14 = 126

What number is less than -2 4/5 and greater than -31/5

IgorC [24]

Using a calculator, you should find that

-2 & 4/5 = -(2 + 4/5) = -(2+0.8) = -2.8

-31/5 = -6.2

So the unknown number is between -6.2 and -2.8

<h3>Possible whole number answers could be: -6, -5, -4, -3, or -2</h3>

If your teacher allows decimal answers, then there are infinitely many possible ways to answer.

Savatey [412]

Answer:

Step-by-step explanation:

Given a triangle with two sides a and b and an included(an angle between the two given sides) angle $\theta,$

Area of the Triangle $=\dfrac12 ab\sin \theta$

$a=32$ miles\\b=23 miles\\\theta =37^\circ$

Therefore, The area of the portion that will not be farmed

$=\dfrac12 \times 32 \times 23 \times \sin \37^\circ\\=221.47\\\approx 221.5$ square miles$

The correct option is C.

What's the answer for (2+i)(i+2i)?

slava [35]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{3 {i}^{2} + 6i}}}}}$

Step-by-step explanation:

$\sf{(2 + i)(i + 2i)}$

Use the distribute property to multiply each term of the first binomial by each term of the second binomial.

⇒ $\sf{2(i + 2i) + i(i + 2i)}$

⇒ $\sf{2i + 4i + {i}^{2} + 2 {i}^{2} }$

Collect like terms

⇒ $\sf{3 {i}^{2} + 6i}$

Hope I helped!

Best regards!
