length of side = 36 cm
let x be the side of the square then x + 8 is the side of the triangle
perimeter of square = 4x and
perimeter of triangle = 3( x + 8 ) + 4 = 3x + 24 + 4 = 3x + 28
equating the perimeters
4x = 3x + 28 ( subtract 3x from both sides )
x = 28
length of side of triangle = x + 8 = 28 + 8 = 36 cm
Answer:
the composite figure consists of two rectangular pyramids, and the total volume is 90 units 3
Step-by-step explanation:
A rhombus is a parallelogram with equal sides
M= 1/3
Remember m is the slope so to find the slope use (-1,-2) (-7,-4)
First,divide 18 by 9.You get 2.That's 1/9,so just multiply 2 by 4(which is 8),and you get you're answer.
