A= (a+b)/2*h
A=(12+15)/2*5
A=(27/2)*5
A=13.5*5
A=67.5in
Answer:
-12
Step-by-step explanation:
x = 12-3a
When a=8:
x = 12-3(8)
x = 12 - 24
x = -12
Answer:
4....
Step-by-step explanation:
Okay! Free points, uh... 2... and 2... put together... is... four...
we can always find the slope of any line by simply using two points on the line, say let's use (3,4) and (-1,2)
![\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{-1}~,~\stackrel{y_2}{2}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{2-4}{-1-3}\implies \cfrac{-2}{-4}\implies \stackrel{\stackrel{\textit{common difference}}{\downarrow }}{\cfrac{1}{2}}](https://tex.z-dn.net/?f=%5Cbf%20%28%5Cstackrel%7Bx_1%7D%7B3%7D~%2C~%5Cstackrel%7By_1%7D%7B4%7D%29%5Cqquad%20%28%5Cstackrel%7Bx_2%7D%7B-1%7D~%2C~%5Cstackrel%7By_2%7D%7B2%7D%29%20%5C%5C%5C%5C%5C%5C%20slope%20%3D%20m%5Cimplies%20%5Ccfrac%7B%5Cstackrel%7Brise%7D%7B%20y_2-%20y_1%7D%7D%7B%5Cstackrel%7Brun%7D%7B%20x_2-%20x_1%7D%7D%5Cimplies%20%5Ccfrac%7B2-4%7D%7B-1-3%7D%5Cimplies%20%5Ccfrac%7B-2%7D%7B-4%7D%5Cimplies%20%5Cstackrel%7B%5Cstackrel%7B%5Ctextit%7Bcommon%20difference%7D%7D%7B%5Cdownarrow%20%7D%7D%7B%5Ccfrac%7B1%7D%7B2%7D%7D)
Answer:
x = 2
y=6
Step-by-step explanation:
6 + 2 = 8
2 + 6 x 2 = 14
Hope this helps
Have a blessed day!
