Answer:

perimeter of square = 35.78 cm

Step-by-step explanation:

cut the rhombus into 4 triangles along the diagonals

each triangle has a base of 5 and a height of 10 cm

area of one triangle = 1/2(4)(10) = 20 cm^2

4 triangles = area of rhombus = 80 cm^2

then the square has an area of 80 cm^2 also

side^2 = 80 cm^2

side of square  = 8.94 cm

perimeter = 8.98 x 4 = 35.78 cm

Introduction to addition or subtraction of fractions with different denominator 3/4-1/8
snow_lady [41]
The denominator must be the same, so just think of the LEAST COMMON MULTIPLE, The LCM here is 8, because you can multiply 4 by 2 to get 8.
so when you multiply, you multiply both on the top and on the bottom, so this would be:
3 x 2 / 4 x 2 = 6 / 8
Now you can add or subtract: 6/8 - 1/8 = 5/8

larisa [96]

Answer:

(x² -7)/(2x + 1)

Step-by-step explanation:

f(x) = 2x+1 and g(x) = x² -7

thus: (g/f)(x) = g(x)/f(x) = x² -7/2x + 1
