Answer:
Step-by-step explanation:
<u>Total surface area:</u>
- S = 2(lw + lh + wh)
- S = 2(20*14+20*10+14*10) = 1240 in²
Step-by-step explanation:
What's the value for a? This cannot be solved unless 'a' or 'n' is given
-2x + y = 8
y = 2x + 8
now sub in 2x + 8 for y in the other equation
3x + 2y = 2
3x + 2(2x + 8) = 2...distribute the 2 thru the parenthesis
3x + 4x + 16 = 2
7x = 2 - 16
7x = - 14
x = -14/7
x = -2
now sub -2 in for x in either equation to find y
-2x + y = 8
-2(-2) + y = 8
4 + y = 8
y = 8 - 4
y = 4
solution is : (-2,4)
