Answer:

No.

Step-by-step explanation:

Let's solve our expression first:

6(2r+(-1)+1

12r + (-6) + 6

12r - 6 + 6

12r - 0

Conclusion:

12r - 0 ≠ 12r - 5

Hope it helped,

Find the area and the perimeter of a quadrant of a circle with radius 4m correct to 3 significant figures

iogann1982 [59]

Area of a quarter circle = 1/4 * pi * r^2

= 1/4 * pi * 4^2 = 12.6 m to 3 sig figs.

perimeter = 4 + 4 + 1/4 * 2 pi * 4 = 14.3 to 3 sig figs.

The number of cell phone minutes used by high school seniors follows a normal distribution with a mean of 500 and a standard dev

prohojiy [21]

<span>The number of cell phone minutes used by high school seniors follows a normal distribution with a mean of 500 and a standard deviation of 50. what is the probability that a student uses more than 580 minutes?

Given
μ=500
σ=50
X=580
P(x<X)=Z((580-500)/50)=Z(1.6)=0.9452
=>
P(x>X)=1-P(x<X)=1-0.9452=0.0548=5.48%

A school is installing a flagpole in the central plaza. The plaza is a square with side length 100 yards as shown in the figure

Goryan [66]

The length of the flagpole is x - 5 yards

<h3>How to determine the length of the flagpole?</h3>

The complete question is in the image

The area of the flagpole is given as:

Area = x^2 - 10x + 25

Expand the expression

Area = x^2 - 5x -5x + 25

Factorize the expression

Area = (x - 5)(x - 5)

Express as squares

Area =(x - 5)^2

The area of a square is

Area = Length^2

So, we have:

Length = x - 5

Hence, the length of the flagpole is x - 5 yards
