Answer:
D. *6F
Step-by-step explanation:
C=(F-32)*5/9
30=(F-32)*5/9
F = (30*9)/5+32
F = 86
Y = x + 5....so we sub in x + 5 for y in the other equation
4x + y = 20
4x + x + 5 = 20
5x + 5 = 20
5x = 20 - 5
5x = 15
x = 15/5
x = 3
y = x + 5
y = 3 + 5
y = 8
solution is (3,8)
-12 and 18
hope this helps :)
So 4x^2+-2x+-6 then multiply by 5 would be the Area of the entire rectangle using the formula A=bh
You'll get 4x^2 − 2x − 6
