To find the length of the base, you must first find the length of the sides, or the value of x. Because it is an isosceles triangle, the legs are equal to each other.
2x + 4=x + 8
x=4
Now that you have found x, plug it into the equation for the base.
5(4) - 2
20 - 2
18
Final Answer: 18
Hope this helps!! :)
<span>Length = the longer side
He wants to build a table with a length of 9ft.
The plans he has are 18ft x 36ft
Length of the plans = 36ft
Compare the length of the plans to the length he wants:
36 ft vs 9 ftThe length in the plans is 4 times longer than the length he wants.<span>
</span>Length he wants / Length of plans = your dilation scale factor
9 / 36 = ¼
1/4 = dilation scale factor
Hope this answers your question, and May the Force Be With You!

Answer:

Step-by-step explanation:
We are required to subtract
.
![[2x^4-8x^2y^2-y^4]-[-6x^4-3x^2y^2+5y^4-6x]](https://tex.z-dn.net/?f=%5B2x%5E4-8x%5E2y%5E2-y%5E4%5D-%5B-6x%5E4-3x%5E2y%5E2%2B5y%5E4-6x%5D)
<u>Step 1:</u> Open the bracket, Take note of the signs
![[2x^4-8x^2y^2-y^4]-[-6x^4-3x^2y^2+5y^4-6x]\\2x^4-8x^2y^2-y^4+6x^4+3x^2y^2-5y^4+6x](https://tex.z-dn.net/?f=%5B2x%5E4-8x%5E2y%5E2-y%5E4%5D-%5B-6x%5E4-3x%5E2y%5E2%2B5y%5E4-6x%5D%5C%5C2x%5E4-8x%5E2y%5E2-y%5E4%2B6x%5E4%2B3x%5E2y%5E2-5y%5E4%2B6x)
<u>Step 2:</u> Collect like terms

<u>Step 3:</u> Simplify

Answer:
How many sides are there?
Step-by-step explanation:
Answer:
Add 19 to both sides
Step-by-step explanation:
In order to isolate X you would need to add 19. To keep the equation equal and balanced, you would then need to add 19 to the other side.
X-19+19 = 1+19
X=20
