PLZ PLZ HELP ITS URGENT!!!! 
arlik [135]
Given:
Equilateral triangle: height = 2.6 inches ; base or side length = 3 inches
Rectangle: length = 6 inches ; width = 3 inches

1 name plate has 2 equilateral triangle and 3 rectangles.
Surface area of an equilateral triangle = √3/4 * a² = √3/4 * 3² = 3.9 in²

3.9 in² x 2 = 7.8 in²

Surface area of a rectangle = 6 in * 3 in = 18 in²

18 in² x 3 = 54 in²

7.8 in² + 54 in² = 61.8 in²

61.8 in² x 30 nameplates = 1,854 in²  Choice A.

Does anyone know how to find the side length of this square.if so then, i will mark brainlist.
kvv77 [185]
Hello!

To find the side length you use the equation

a =  \sqrt{2}  \frac{d}{2}

a is side length
d is diagonal

Put in the number we know

a =  \sqrt{2} *  \frac{27}{2}

Divide

a =  \sqrt{2} * 13.5

Multiply

a = 19.091

The answer is 19.09

Hope this helps!

9x+18+3x=1
Katen [24]
The error is in the second step they subtracted 3 from both sides but it was a 3x, which you can not do.
Correction.
9x+18+3x=1
12x+18=1
12x=-17
x=-17/12
