Answer:

I'm wrong!

Step-by-step explanation:

2x+5<-17

Subtract five from both sides

2x<-22

Divide both sides by 2 and remember to flip the sign when you divide

x>-11 is wrong

My answer is wrong because you flip the sign when you divide by a negative number.

x<-11 is correct

If x³ + 2x and x³ − 7x² + 4x +2 + k have a common linear polynomial factor, then the value of k is what?

Georgia [21]

Answer:

k = -2

Step-by-step explanation:

<u>Factor x³ + 2x:</u>

x³ + 2x = x(x² + 2)

1. <u>The common factor is x, then</u>:

2 + k = 0 ⇒ k = -2 (all the rest are divisible by x)

2. Factor x² + 2 is not linear therefore we discard it.

The rectangle below has an area of 144x4 square meters and a width of 12x meters. What is the length of the rectangle?

Alex777 [14]

<h3>The length of rectangle is 12x³ metres .</h3>

As we know that

♦ Area of rectangle = Length × breadth

Substituting known values ,

⇒ 144x⁴ = 12x ( Length )

⇒ 144x⁴ / 12x = Length

⇒ 12x³ = Length

⇒ Length = 12 x³

Max built a skateboarding ramp that is 16 inches high. The angle formed by the ramp and the ground is 21 . What is the length of

natali 33 [55]

Answer:

41.68 or 42 (rounded)

Step-by-step explanation:

Presuming you are working on right triangles, you can use the Soh Cah Toa theorems.

Because angle A = 21 and side a = 16 you can use Toa or $A=\frac{a}{x}$

$21=\frac{16}{x}$

Plugged into a calculator, you get 41.68 and some change.

If this is NOT a right triangle question, please let me know so that I can revise my answer.
