P(x) = x^2 + 4x
y = x^2 + 4x
use the formula (b/2)^2 to find the new c value
(4/2)^2 = 4
add 4 to both sides
y + 4= x^2 + 4x + 4
y + 4= (x+2)^2

y= (x+2)^2 - 4

Answer:

76%, $\frac{19}{25}$ , and Likely

Step-by-step explanation:

The problem tells us that P(red) = 0.76

0.76 as a percentage is represented as 76 out of a 100 or 76%

0.76 as a fraction is $\frac{76}{100}$ which can be simplified to $\frac{19}{25}$ by dividing the numerator and denominator by 4

The probability could be considered "Likely" as it is above 50%

How many solutions can be found for the equation 5x + 3(x − 1) = 10x − 2x − 3?

Lady_Fox [76]

Infinitely many solutions. Since your slope and Y axis values are the same on both sides no matter what you fill in for x your answer will be true.

What is the perimeter, in square centimeters, of a rectangle that has a length of 4 centimeters and a width of 15 millimeters? 3

Scorpion4ik [409]

Answer:

11 cm

Step-by-step explanation:

The rectangle width is 15 mm, which is the same as 1.5 cm.

The formula for P is P = 2W + 2L.

Here, with W = 1.5 cm and L = 4 cm, P = 2(1.5 cm) + 2(4 cm) = 11 cm
