Answer: d) 14
Step-by-step explanation:
Equation of a line passing through (a,b) and (c,d):

Equation of a line passing through (2, 18) and (–3, 8):

Comparing resulting equation
to
, we get value of b= 14.
Hence, correct option is d) 14
1. Box off the squares (which you did)
2. Solve the area of the squares: (10cm x 10cm = 100cm each square)
3. Solve the area of the rectangle that is left: (you would do 40cm x 10cm since the other 10cm went with the square. The rectangle should end up to be 400cm.
4. Add the areas: 100cm + 100cm +400cm = 600cm
600cm is the answer
Step-by-step explanation:
Consider the provided statement.
If we lose electricity, then the data will be lost.
We are need to write the negation of the above statement.
First divide the whole statement in two parts
Let us consider p = We lose electricity and q = The data will be lost.
The symbol use for negation is tilde 


Represent T for true and F for False.
The required table is shown below:
p q 
F F F
F T F
T F T
T T F
Hence the required table is shown above.
Answer:
12r^2 +r -7
Step-by-step explanation:
9r^2 +4r -7 +3r^2 -3r
Combine like terms
9r^2 +3r^2 +4r -3r -7
12r^2 +r -7
I hop this is right number 3
