Assuming we want to factor the formula to (x+3)(x+3), you want to have a +9 where there is a -4 now. So you must add 13.
Answer:
40
Step-by-step explanation:
PEMDAS
Do what is in the parentheses first.
-8 * -9 = 72
-9 - 8 + (72) - 15
-9 - 8 - 15 = -32
-32 + 72 = 40
Answer:
The engine size would be 3.0 litre
Step-by-step explanation:
The given parameters are;
Volume of engine = 2.0 litre
Number of cylinders = 4
Capacity of each cylinder = 500 cc
Therefore, when 2 more 500 cc cylinders are added, the size of the engine which is the total volume of combustion gases that can be handled by the cylinders of the engine becomes;
Engine size = Total volume of engine cylinders
New engine size = (4 + 2)×500 cc = 3000 cc = 3.0 litre.
The slope of the equation would be 7/3 since the original slope was -3/7. We already know y int (b) so the eqn is
y = 7/3x + 2
