Will mark BRAINLIST Find the perimeter of the following shape, rounded to the nearest tenth: coordinate plane with quadrilateral

kolbaska11 [484]

Answer:

11.3 units

Step-by-step explanation:

Let's find the length of one of the boxes.

$a^2+b^2=c^2\\1^2+1^2=c^2\\1+1=c^2\\2 = c^2\\\\\sqrt{2} = c\\ c = 1.414...$

Let's simplify c down to 1.41.

Now, there are 8 of these little boxes for the perimeter, let's multiply.

$1.41\cdot8=11.28$

That can be simplified to the nearest tenth - 11.3

Hope this helped!

NEED DONE ASAP!!

almond37 [142]

Answer:

A. 3x^2 + 4 = 52

3x^2 = 52 - 4

3x^2 = 48

x^2 = 48/3

x^2 = 16

x = $\sqrt{16}$

x = 4

B. x^2 - 121 = 0

x^2 = 121

x = $\sqrt{121}$

x = 11

C. (b + 4 )2 = 49

2b + 8 = 49

2b = 49 - 8

2b = 41

b = 41/2
