Answer:

Area: 312

Perimeter: 75

Step-by-step explanation:

Area is l·w

20·16=320

two corners aren't filled

320-9-9=318

Add all the sides for perimeter

17+3+3+13+20+13+3+3=75

Answer:

281 m squared

Step-by-step explanation:

What we can first do is find the top length so we can do

17+3+3=23

then we can multiply it by the side length to get the whole rectangle

23*13=299

and we know each of the little areas is 9, and there are two so

9+9=18

and we can subtract that from the whole rectangle

299-18=281

Solve (9x-4)^2=18 using the square root method
Damm [24]

Answer:

x = 4/9 + sqrt(2)/3 or x = 4/9 - sqrt(2)/3

Step-by-step explanation:

Solve for x over the real numbers:

(9 x - 4)^2 = 18

Take the square root of both sides:

9 x - 4 = 3 sqrt(2) or 9 x - 4 = -3 sqrt(2)

Add 4 to both sides:

9 x = 4 + 3 sqrt(2) or 9 x - 4 = -3 sqrt(2)

Divide both sides by 9:

x = 4/9 + sqrt(2)/3 or 9 x - 4 = -3 sqrt(2)

Add 4 to both sides:

x = 4/9 + sqrt(2)/3 or 9 x = 4 - 3 sqrt(2)

Divide both sides by 9:

Answer: x = 4/9 + sqrt(2)/3 or x = 4/9 - sqrt(2)/3

Which expression gives the distance between the points (-3,4 and (6,-2)
krok68 [10]

Answer:

10.8

Step-by-step explanation:

We can find the distance using the distance formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

We then substitute (-3,4) as (x_1,y_1) and (6,-2) as (x_2,y_2).

d=\sqrt{(6--3)^2+(-2-4)^2} \\d=\sqrt{(9)^2+(-6)^2} \\d=\sqrt{81+36}\\d=\sqrt{117}=10.8
