Answer:
-2c^2 + c
Step-by-step explanation:
Answer:
A = 110.25
Step-by-step explanation:
add all the equations and equal it to 180 because all triangle angles add to 180:
4x+1 + 3x + 3x-1 = 180
10x =70
/10 /10
x = 7
Insert x into each equation and solve:
3(7)-1 = 20
4(7)-1 = 27
3(7) = 21
and then use A = 1/2 base*height formula:
A= 1/2 21* 20
A= 210
L= 2+w
I cannot solve this, however, because you have not included the total perimeter/area
Distraibutiv peorpoty
a(b+c)=ab+ac
we have
3a+7+2(3+a)
distribute first
2(3+a)=6+2a
now we have
3a+7+6+2a
move like terms together
3a+2a+7+6
add lke terms
5a+13
