Just distribute the 3. 3(x + 4y) = 3x + 12y
3x + 12y is the answer.
X - 24 = x /9
multiply through by 9:-
9x - 216 = x
8x = 216
x = 27 answer
Answer:
multiply s by t
Step-by-step explanation:
you just multiply s times t and get your answer
Answer:To find out the Area of a scalene triangle whose three sides are given, first find out the half perimeter
s = (a+b+c)/2
where a, b, and c are the length of the three sides of a triangle
s = (35 + 45 + 50) / 2
= 130 / 2
= 65 cm
Area of scalene triangle is given by
A = sqrt (s (s - a) (s - b) (s - c))
= sqrt (65 * (65 - 35) ( 65 - 45) (65 - 50))
= sqrt (65 * 30 * 20 * 15)
= sqrt (585000)
= 764.853 sq cm
