6 0

|2x + 4| = 8

break down into two equations;

2x + 4 = 8 -(2x + 4) = 8

2x = 8 - 4 -2x - 4 = 8

2x = 4 -2x = 8 + 4

x = 2 -2x = 12

x = -6

so the answer is B) x = -6 or x = 2

hope this helped, God bless!

In Jack's class, 7 out of 25 students have hazel eyes. What percent of the class has hazel eyes?

denis23 [38]

You're going to set up a proportion. % over 100 = is over of. You're looking for the percent so that's your x. X over 100=7 over 25. Cross multiply to get 25x=700. Divide both sides by 25 and your answer is 28%

A pizza parlor offers pizzas with diameters of 8 in, 10 in, and 12 in. find the area of each size pizza. round to the nearest te

MaRussiya [10]

Area od pizza, A = Pi*Diameter^2/4

A1 = Pi*8^2/4 = 50.27 in^2
A2 = Pi*10^2/4 = 78.54 in^2
A3 = Pi*12^2/4 = 113.10 in^2

Cost (C) per sq. in;
C1 = 50.27/9 = $5.59
C2 = 78.54/12 = $6.55
C3 = 113.10/18 = $6.28

The best buy is the first pizza with 8 in diameter as it costs the least per sq. inch.

EXPLANATION

The numbers are given in standard form.

The first criteria we will use to order them is the exponents.

The bigger the exponents the bigger the number.

The second criteria is that, if the exponents of any two numbers are the same, then we use the numbers multiplying the powers of 10 to order.
