There are infinitely prime numbers "p", but p+2 and p+4 are not primes.

Example: Suppose p = 7 (prime) if you add 2, it becomes 9 (Not a Prime).
 Same thing if p = 11(prime), if yo add 4, it becomes 15 (Not a prime number)

ella [17]

Answer:

Answer is y = 2x - 3

Step-by-step explanation:

• Equation of parallel lines have the same slope. So first two equations are okay.

• For point (1, -1):

{ \rm{y = mx + c}} \\ { \rm{ - 1 = 2 + c}} \\ { \rm{c =  - 3}}

• Equation is y = 2x - 3

One liter of paint covers 100 square feet. a wall that measures 32 feet by 16 feet is going to be painted.
lubasha [3.4K]
A) The wall = 32ft * 16ft = 512 square feet.
If one liter of paint covers 100 square feet then you're going to need 6 liter of paint because 5 liters could only cover 500 square feet so it wouldn't be enough. So you get the formula Liter * 0.26417 = gallons and plug in the 6 liter to get <span>1.58502 gallons

B) From the answer above you can estimate that you would need 2 gallons

C) Remember that you had 6 liters of paint which = 600 square ft. So you have 600 square ft of paint - 512 square ft wall = 88 square ft unused paint. And if one liter = 100 square ft, x liters = 88 square ft. So to get the liter you get the equation 100x=88  --> x=88/100
So the ANSWER is .88 liters of paint will be left remaining in the container.</span>
