Answer:
x = 3
Step-by-step explanation:
The angle bisector divides the segments either side of it proportionally. So, you have ...
x/4 = 2.25/3
x = 4·2.25/3 . . . . multiply by 4
x = 3
_____
Since DB = 3 and DA = 2.25, point D is clearly <em>not the midpoint</em> of AB.
I think you forgot to put a sign for g(x)
If g(x)=f(x) +3 then the answer is a
If g(x)=f(x) -3 then the answer is c
Answer:
the answer is 14.7
Step-by-step explanation:
The perimeter of triangle XYZ is 24 units.
Triangle X Y Z is shown. The length of X Y is 3 and the length of Y Z is 11. Angle Y X Z is 102 degrees
What is the area of triangle XYZ? Round to the nearest tenth of a square unit.
Trigonometric area formula: Area
14.7 square units
14.9 square units
15.0 square units
15.3 square units
Answer: 40 + 24x
Step-by-step explanation: I'm guessing that the equation is addition. You have to add similar numbers. 35 + 5 is 40. 8x + 16x is 24x.
Answer: 125%
Step-by-step explanation:
The ratio of the width to the length of a rectangle is 2:3, respectively , this means that :
W = 
L
Area of a rectangle = Length X Width , this means that
A = L X L
A = 
The Length and the Width increased by 50% , this means that :
New Length = 1.5L
New Width = 1.5W
New area = 1.5L x 1.5 W
New area = 2.25WL
But W = L , therefore :
New Area = 2.25L( L )
New Area = 1.5
Therefore , % change in area = change in area / original area x 100
Change in area = 1.5 -
% change in area = 0.833/0.677 x 100
% change in area = 125%
