*I apologize for the late response, if any of you need this, I'm happy to help. If the explanation isn't clear, please message me and we can work from there. I have checked this answer 3 times and it has been correct all those three times.*

Question and procedure:

√3 x 2√2 x 5√8 x √18

To solve, first, you should simplify any roots that need simplifying.

The two roots that need simplifying are 5√8 and√18.

In 5√8, you can still simplify the √8, there are four factors of 8: 1,2,4,8. The only two factors that you will be able to further simplify are 2 and 4.

TO SOLVE:

√2 x √4 = 2√2

then, you multiply 2√2 x 5, getting you 10√2

( the root of 4 is 2)

THE OTHER ROOT:

√18: 18 has the following factors: 1,2,3,6,9,18. The two factors that you will be able to further simplify are 9 and 2.

So, √18 is 3√2.

Now we can solve the problem:

√3 x 2√2 x 10√2 x 3√2

( when solving, it is important to keep in mind that you are supposed to multiply the number OUTSIDE the root together and the numbers INSIDE of the root together)

√3 x 2√2 = 2√6.

2√6 x 10√2 = 20 √12

* WE ARE ABLE TO SIMPLIFY 20√12 into 40√3.

40√3 x 3√2 = 120√6.

Complete Question

Which could be the area of the base of the triangular prism?

[Not drawn to scale)

• 6 ft²

• 10 ft²

• 12 ft²

• 20 ft²

Answer:

6ft²

Step-by-step explanation:

The formula for the base area of a triangular prism is given as:

Area of the base = √s(s-a) (s-b) (s-c)

Where s = (a+b+c)/2

From the attached diagram,

a = 5ft

b = 3ft

c = 4ft

s= (5ft + 3ft + 4ft) ÷ 2

s = 6ft

Area of the base = √ 6( 6-5) (6-3) (6-4)

= √6(1)(3)(2)

= √36

= 6ft²

Therefore, the area of the base of the triangular prism is 6ft²

Answer:

23/3 cubic units

Step-by-step explanation:

The volume of a prism is the product of its base area and it height:

V = (23/4 units^2)(4/3 units) = (4·23)/(4·3) units^3 = 23/3 units^3

If 30(x-10)=120 then x=

Crazy boy [7]

30(x - 10) = 120

Use distributive property to remove the parenthesis
30x - 30(10) = 120
30x - 300 = 120

move the constant to the right side
30x - 300 = 120
30x = 120 + 300
30x = 420

solve for x by moving 30 to the right side, multiplication will be division after moved to the right side
30x = 420
x = 420/30
x = 14

The value of x is 14
