Answer:

2(4 + 2z) = 8 + 4z

2(4 + 2z) = 0

z = -2

Step-by-step explanation:

How to solve:

2(4 + 2z)

Distribute:

2(4 + 2z)

2(4) + 2(2z)

Multiply:

2(4) + 2(2z)

8 + 4z

8 + 4z is the simplified expression.

How to solve:

2(4 + 2z) = 0

Distribute:

2(4 + 2z) = 0

2(4) + 2(2z) = 0

Multiply:

2(4) + 2(2z) = 0

8 + 4z = 0

Subtract 8 on both sides:

8 + 4z = 0

-8 -8

4z = -8

Divide by 4 on both sides:

4z = -8

/4 /4

z = -2

z = -2 is the answer if 0 is on the other side of the equal sign

Answer: It would be 8+4z because you can't add a variable.

Ilya [14]

Answer:

The equation could be used to find the dimensions of the window would be: $w^{2} + 5w = 36$

Step-by-step explanation:

The length of a rectangular window is 5 feet more than its width, w.

and

The area of the window is 36 square feet.

So it means

$l = w + 5$

$A = lw$

$36 = (w + 5)w$

$w^{2} + 5w = 36$

Therefore, the equation could be used to find the dimensions of the window would be: $w^{2} + 5w = 36$

Two airplanes are flying to the same airport. Their positions are shown in the graph. Write a system of linear equations that re

wariber [46]

Answer:

Airplane #1 equation: y=5/13x+42/13

Airplane #2 equation: y=1/3x+14

Step-by-step explanation:

So to find the slope of each airplane, you use the formula y2-y1/x2-x1. That means, for airplane#1 the equation will be 9-4/15-2. Simplify this and get 5/13. Then, for airplane#2, the equation will be 12-9/6-15. Simplify this and get 3/-9 and divide each side by 3 to get 1/-3 or -1/3. Next, use point slope formula to find the system of linear equations. Point slope formula is y-y1=m(x-x1). M is the slope. Use any point from the line. In this case, I will use (2,4). Tat means the first airplane's equation would be y-4=5/13(x-2). Then y-4=5/13x-10/13. Then, convert four into a fraction with a denominator of 13. This means, you have to multiply 4 by 13 to get 52/13. Add 52/13 to -10/13 to get 42/13. That means the first equation will be y=5/13x+42/13. The second equation point will be (6,12). This means the equation will be y-12=-1/3(x-6). Simplify this to get y-12=-1/3x+2. Simplify this to get y=1/3x+14. Therefore, Airplane#1 equation will be y=5/13x+42/13 and airplane #2 equation will be y=1/3x+14.
