Answer:

Perpendicular

Step-by-step explanation:

If you look at the image, it shows a rectangular prism. The line CD is next to the line AD. It is perpendicular because someone could draw a right angle where the lines CD and AD meet.

I Hope That This Helps! :)

Use synthetic division to find the result when 3x^3 + 13x^2 + x – 12 is divided by<br> X + 4.

IgorC [24]

Answer:

3x² + x - 3

Step-by-step explanation:

The way I like to do it is to get rid of the x's and just use the numbers in the case of synthetic division

Pretend the square root of the division symbol

-4 √ 3 12 1 -12

Quick note: We're dividing by -4 because we're dividing by x + 4

First bring down the 3

-4 √ 3 13 1 -12

Multiply it by 4 then bring add it to the next number

-4 √ 3 13 1 -12

-12

3 1

Add that number to the next one

-4 √ 3 13 1 -12

-12 -4

3 1 -3

Finally repeat the step for the last number

-4 √ 3 13 1 -12

3 -12 -4 +12

3 1 -3 0

Now take those bottom numbers and add back the x's but with one less power, so the starting x³ would now become x², x² would become x, and so on

3x² + 1x - 3

Metal A has a density of 12.7 g/cm3.

stira [4]

Using the given information, the density of metal B is 8.58 g/cm³

<h3>Calculating density </h3>

From the question, we are to determine the density of metal B

From the given information,

55 g of metal A is combined with metal B to create an alloy with mass 90 g

∴ Mass of metal B in the alloy = 90 g - 55 g = 35 g

Now, we will determine the volume of metal A in the alloy

Using the formula,

Density = Mass / Volume

∴ Volume = Mass / Density

Volume of metal A in the alloy = 55/12.7

Volume of metal A in the alloy = 4.33 cm³

Then, we will determine the volume of the alloy

Volume of the alloy = 90/10.7

Volume of the alloy = 8.41 cm³

∴ Volume of metal B in the alloy = 8.41 cm³- 4.33 cm³

Volume of metal B in the alloy = 4.08 cm³

Now, for the density of metal B

Density = mass / volume

Density of metal B = 35 / 4.08

Density of metal B = 8.58 g/cm³

Hence, the density of metal B is 8.58 g/cm³.

Tyler tried to solve an equation stop by step

maks197457 [2]

Answer:

Tyler didn't make a mistake

Step-by-step explanation:

3(x+4)=-18

(x+4)=-18/3 (divide by 3 on both the sides)

x+4=-6

x=-6-4 (subtract 4 from both the sides)

x=-10
