2x + 2x + 32 = 256

-32

2x+2x = 224

4x=224

/4

x= 56





lenght = width+16

perimeter = width + width + (width + 16) + (width + 16)

perimeter = x + x + (x+16) + (x+16)

perimeter = 2x + 2((x+16)



therefore width = 56 
length = 72

What is the slope of the line?<br><br> A: 3<br><br> B: - 3<br><br> C: - 1<br><br> D: 1
Shtirlitz [24]

Answer:

A

Step-by-step explanation:

To find the slope of a line, we can use the slope formula:

\displaystyle m=\frac{y_2-y_1}{x_2-x_1}

So, we will need to choose two points from the graph. Any two points will work.

Let’s choose (0, -1) and (1, 2).

So, we will let (0, -1) be (x₁, y₁) and (1, 2) be (x₂, y₂). Substitute these values into the slope formula:

\displaystyle m=\frac{2-(-1)}{1-0}

Evaluate:

\displaystyle m=\frac{3}{1}=3

Therefore, the slope of the line is 3.

Hence, our answer is A.

What is the perimeter of 2m 10cm by 45 cm
qwelly [4]
I believe it is 510 cm because a meter equals 100 cm so 210 cm times 2 equals 410 cm then multiply 45 times 2 and get 90 cm then add 410 plus 90 and get 510 cm.
