Answer:

c=2

Step-by-step explanation:

(ax+2)(x+b) = ax^2+2x+abx+2b = ax^2+(2+ab)x+2b

Given, ax^2+(2+ab)x+2b = 3x^2+5x+c

a=3

2+ab=5 => 2+3b=5 => 3b=5-2=3 => b=1

2b=c => c=2*1 = 2

So, c=2

PLEASE HELP!!!! The problem is in the photo below.

Answer:

A is correct.

Step-by-step explanation:

Here, the x would represent the gallons per minute. The minutes are unknown, so it's just a variable. It can't be B either, because the addition sign would mean that the pool is being filled instead of drained.

You are in charge of the Annual Powder Puff football game. You designed a t-shirt to sell during the event. A company charges $7
vekshin1
We're looking for C(h), where h is the hundreds of shirts.  The fact that they cost "$500 for each additional 100 t-shirt" tells us the slope is 500.  Knowing that 1 hundred costs 750, we could use point-slope at this point: (C - 750)/(h - 1) = 500C - 750 = 500h - 500C(h) = 500h + 250 We can check that C(1) = 750 and C(2) = 1250, as we expect.  I'll leave it to you to evaluate C(5).

kakasveta [241]

Answer:

j - 10 = 35

Step-by-step explanation:

Given: 10 less than j is 35.

To find: The equation of the given situation.

Solution: We need to write an equation for 10 less than j is 35.

Here, we will break down the sentence to form the equation.

10 less than j means j - 10.

Then, it says 10 less than j is 35 which means it is equal to 35.

So, the sentence 10 less than j is 35 can be written as 10 less than j is equal to 35.

Now, 10 less than j is equal to 35 can be shown as j - 10 = 35.

Therefore, the required equation is  j - 10 = 35.
