X=first number
2x= second side
3.5x= third side
X+2x+3.5x=65
6.5 x= 65
Divide both sides by 6.5
X=10. First side
2x= 20. Second side
3.5x= 35 = third side
10, 20, 35
Answer:
Q2) 6x4=24
24 +3 =27
Step-by-step explanation:
Answer:
3,4,5
Step-by-step explanation:
3 + 4 + 5 = 12
To find the range, you need to locate the vertex:
equation for vertex = ax^2 + bx +c
in x^2 + 3, a = 1, b = 0 and c = 3
now vertex form = a(x+d)^2 +e
d = b/2a = 0/2*1 = 0
e = c-b^2/4a = 3-0^2/4*1 = 3
The equation becomes: (x+0)^2 +3.
The range is Y ≥ 3 ( greater than or equal to 3)
Answer:
<x = 53 degrees
Step-by-step explanation:
<Q = 62 degrees (alternate angle)
<PRQ = 180-115 (Angles on a straight line add up to 180 degrees)
<PRQ = 65 degrees
<u><em>Now, Finding <x</em></u>
To find <x, we'll simply subtract 180 from rest of the triangles interior angles because the interior angles of a triangle add up to 180 degrees
=> <x = 180-65-62
=> <x = 53 degrees
