S=(10)(1/2)+(1/2)(-2)(1/2)^2
s=5+(-1)(1/4)
s=5-(1/4)
s=4 and 3/4 or 19/4
Step-by-step explanation:
3(3u-5)=39
9u - 15 = 39
9u = 15 + 39
9u = 54
divide both by 9
u = 54/9
u = 6

Answer:
Step-by-step explanation:
X = whole number
Z = fraction numarater
Y = fraction denometer

Y/1 = Y
C/Y
The length of the missing side of the triangle is 6 cm.
<h3>
Triangle</h3>
A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, equilateral, obtuse and scalene triangle.
The perimeter of a triangle is the sum of all the sides of the triangle. Let x represent the missing length. Also, let the other sides be 3 cm and 10 m.
Hence:
Perimeter = x + 3 + 10
19 = x + 13
x = 6 cm
The length of the missing side of the triangle is 6 cm.
