Mathematics
1 answer:
Fofino [41]3 years ago
4 0

Answer:

3(x + 5)²

Step-by-step explanation:

3x² + 30x + 75

3[x² + 10x + 25]

3[x² + 5x + 5x + 25]

3[x(x + 5) + 5(x + 5)]

3[(x + 5)(x + 5)]

3(x + 5)²

If (x) = 3x - 5 and g(x) = x + 3, find (f - g)(x).
Temka [501]

Answer:

2x -8

Step-by-step explanation:

f (x) = 3x - 5

g(x) = x + 3,

(f - g)(x) = 3x - 5 - ( x+3)

Distribute the minus sign

            = 3x-5 -x-3

Combine like terms

           = 2x -8

Mrrafil [7]

Express all possible lengths for this scrap as a compound inequality will be L ≤ 24.

<h3>What is inequality?</h3>

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

To repair a leak a plumber needs a pipe that is within 3/4 of an inch of 32 inches.

⇒ 3/4 x 32

⇒ 24

He already has a 48-inch pipe.

Let the variable L represents the length of the extra (scrap) that is removed from the 48-inch pipe will be

Then express all possible lengths for this scrap as a compound inequality will be

L + 24 ≤ 48

       L ≤ 48 - 24

       L ≤ 24

More about the inequality link is given below.

WILL MRK BRAINLIEST... NEED CORRECT ANSWER..
Rus_ich [418]

Answer:

y= 2/3x +1

Step-by-step explanation:

The y intercept is 1   It crosses the y axis at 1.  So the point is (0,1)

Another point on the line is (3,3)

We can calculate the slope

m = (y2-y1)/(x2-x1)

  = (3-1)/(3-0)

   =2/3

The equation for a line is y=mx+b  where m is the slope and b is the y intercept

y= 2/3x +1
