150 leaves -----100 %
177 leaves ----- x %
------------------------------
150 : 177 = 100 : x
x = ( 177 * 100 ) : 150
x = 118 %
118 5 - 100 % = 18%
Answer: Her collection increased by D ) 18 %
Hello!
7/10 as a decimal is .70
Hope this helps
You need to split the shape up into separate pieces so you can find their areas easily. I have shown this and the working out in the picture.
To find the measurements of the sides of the triangles, I just did 7-6=1 and 14-8=6 to find the missing lengths. So, your answer is 90 units^2
ANSWER: Exact Form:
Decimal Form: 3.16227766
STEP-BY-STEP EXPLANATION:
(1, 2) and (4,3)
Use the distance formula to determine the distance between the two points.
Distance = \sqrt{(X2-X1)^{2 }+ (Y2-Y1)^{2} }
Substitute the actual values of the points into the distance formula.
\sqrt{(4-1)^{2 }+ (3-2)^{2} }
The result can be shown in multiple forms.

6x + x + x - 5 - 2 = 8 + 2x + x
combine like terms
8x -7 = 8 +3x
subtract 3x from each side
5x -7 = 8
add 7 to each side
5x = 15
divide by 5
x=3
Answer: 8x -7 = 8 +3x
x=3
