You got it correct
about + - 10.4
Step-by-step explanation:
y = 2x + 3
When x = 2
y = 2.2 + 3
y = 4 + 3
y = 7
When x = 0
y = 2.0 + 3
y = 0 + 3
y = 3
When x = -2
y = 2.(-2) + 3
y = -4 + 3
y = -1
When x = -4
y = 2.(-4) + 3
y = -8 + 3
y = -5
When x = -7
y = 2.(-7) + 3
y = -14 + 3
y = -9
Either multiply length by width, or measure all sides and add together
LxW=Area
S1+S2+S3+S4=Area
Answer:
80 hours for 2 workers to build 8 cars
