Figuring out volume is simple! There is a formula! It is Length x Width x Height.
V=LxWxH
V=13x6x2.5
V=195in3

The volume is 195in3

Good luck! And No problem.

QUESTION POSTED AT 28/02/2020 - 06:13 AM

Rewrite the following expression 15+21 using the GCF and the distributive property

Answer:

3(5+7)

Step-by-step explanation:

We are asked to rewrite 15+21 using the GCF and the distributive property.

We know that greatest common factor of 15 and 21 is 3.

15=3\times 5 and 21=3\times 7.

We can rewrite our given expression as:

3\times 5+3\times 7

Now, we will factor out 3 from our expression as:

3(5+7)

Therefore, after rewriting our given expression using the GCF and the distributive property we will get 3(5+7).

20 POINTS AND BRAINLIEST ANSWER: Somebody please help on number 7 & 9. I kind of want to know HOW to do it, so I can complete the rest of the worksheet.

I'm so sorry, I only know what question 7 is talking about:
Let's solve your equation step-by-step.
−14x+2=x−3(Solve Square Root.)
−14x+2=x−3−14x+2=(x−3)2(Square both sides)−14x+2=x^2−6x+9−14x+2(x2−6x+9)=x^2−6x+9(x^2−6x+9)(Subtract x^2-6x+9 from both sides)
−x^2−8x−7=0(−x−1)(x+7)=0(Factor left side of equation)
−x−1=0 or x+7=0(Set factors equal to 0)
x=1 or x=−7Check answers. (Plug them in to make sure they work.)
x=−1(Doesn't work in original equation)
x=−7(Doesn't work in original equation)
Answer:No solutions.

For #9...
Let's solve your equation step-by-step.
4(x−3)(1/2)=8
Step 1: Simplify both sides of the equation.
4(x−3)(1/2)=8
Simplify: (Show steps)
2x−6=8
Step 2: Add 6 to both sides.
2x−6+6=8+6
2x=14
Step 3: Divide both sides by 2.
2x2=14
2
x=7
Answer:x=7
Really hope this helps!!!:)

A helicopter fies east 15 miles then south 36 miles. How far is the helicopter from its original​ position? Use the Pythagorean theorem.

Pythagoras is A squared + B squared= C squared (C is always the slanted side!!)

So you do 15 squared + 36 squared (which is 225+1296)= C squared.
You add A squared and B squared together (which is 1521) then square route that number to get your distance from original position. Hope this helps :)
