Match both sides so they're the same
3*y*5*b*10 = 3*y*5*b*10
it's just 3y
Answer:
Step-by-step explanation:
Set this up as a proportion, with width on the top of the ratio and length on the bottom and fill in according to the info you've been given:
![\frac{w}{l}:\frac{5}{8}=\frac{x}{12}](https://tex.z-dn.net/?f=%5Cfrac%7Bw%7D%7Bl%7D%3A%5Cfrac%7B5%7D%7B8%7D%3D%5Cfrac%7Bx%7D%7B12%7D)
x is the unknown width we are looking for. Cross multiply to get
8x = 60 so
x = 7.5
Ms Girl we on the Same Note tbh
The surface area of what shape exactly?
Answer:
R(x) - S(x) = 9x + 5

Step-by-step explanation:
<u>Step 1: Define</u>
R(x) = 6x - 3
S(x) = -3x - 8
<u>Step 2: Find</u>
- Substitute in functions: R(x) - S(x) = 6x - 3 - (-3x - 8)
- [Distributive Property] Distribute negative: R(x) - S(x) = 6x - 3 + 3x + 8
- [Addition] Combine like terms: R(x) - S(x) = 9x + 5
