Finally:

The value of 3ab+5b-5 is 18
Answer:
The first ones area is 35 cm squared
The third ones area is 32 cm squared
Step-by-step explanation:
A=1/2H (B1+B2)
35=2.5(8+6)
32=2(7+9)
Answer:
Step-by-step explanation:
y = mx + b
Take any two points and set up 2 equations with 2 unknowns.
I'll start with the first two
y = 4x + b
410 = 4x + b (1)
440 = 6x + b (2)
Subtract (1) from (2)
440 = 6x + b
<u>410 = 4x + b</u> Subtract
30 = 2x Divide by 2
30/2 = 2x/2
x = 15
440 = 6(x) + b
440 = 6*15 + b
440 = 90 + b
b = 350
Now here is what you found.
