Answer:

46

Step-by-step explanation:

The complete square starting with x^2+14x would be x^2+14x+49, since the square would be (x+7)^2. To make this square perfect, then, you would need to add 46 to make 49 with the 3. Hope this helps!

Write an inequality comparing the rational numbers -3/4 and -2.
lyudmila [28]

Answer:

Step-by-step explanation:

-2 < -3/4.  Another way in which to do this would be to use the LCD:

-8/4 < -3/4.

Even though 8 has a larger magnitude than does 3, -8/4 is smaller than -3/4.  On the number line, -8/4 (or -2) is to the left of -3/4.

I need help with this math problem
mr Goodwill [35]

Let X = number of minutes.

Plan A = 50 + 0.04X

Plan B = 60 + 0.02X


50 + 0.04X = 60 + 0.02X

Subtract 50 from each side:

0.04X = 10 + 0.02X

Subtract 0.02X from each side:

0.02X = 10

Divide both sides by 0.02

X = 10 / 0.02

X = 500

It will take 500 minutes.
