Answer:
The three expressions are the first option, the third option, and the forth option
Step-by-step explanation:
I don't really know how to explain my math lol but I solved 5(1/3x+7)-3(1/2x-), and got x, and plugged in x to the equation. I got my answer, and plugged in x to the rest of the equations and the first one, third one, and fourth ones were the ones that had equal answers. You may want to check my math though because i am not the best but that is what I got.
Y = 4x + 4
-8x + 3y = 5
-8x + 3(4x + 4) = 5
-8x + 12x + 12 = 5
-8x + 12x = 5 - 12
4x = -7
x = -7/4
y = 4x + 4
y = 4(-7/4) + 4
y = -7 + 4
y = -3
solution is (-7/4,-3)
1. I would multiply the dimensions of each room to find the area of each room. Then I can add up the areas to get the total area.
2. (24.5x16)+(15x12.75)+(10.5x10.5)
3. 392+191.25+110.25 = 693.5 ft²
Answer:
(y^2)^5 · y^8 = y^10 * y^8 = y^18
Hope this helps and not to late. Have a great day!
Answer:
5a^2+22a+8
Step-by-step explanation:
5a(a+4)2(a+4)
Then you times each of the brackets
5a^2+20a
+2a +8
____________
=5a^2 +22a +8
and that's ur answer. I like to line it up so it's easier. I don't know if u meant by this but yeah I think it is right
